Rexo’s USP used to be bloodfury, waaay back in the past it was the only monster that had it and as a result it was an insane sweeper. Nowadays it’s a relatively common move used on several legendaries and so Rexo is just outdated.
And yes he’s frail. But then so are most sweepers. At least they have something to offer besides the sweeping ability. Rexo only has the damage, that’s it.
And his damage is unteliable too. Set it up with luck or non-guaranteed stun.
I disagree with the “most other sweepers are frail”:
Survivable sweepers:
Revanarchion has phoenix revenge.
Terragar has sacrifice heal
Flarevern, tiamazus, and omegasdragon have 4k+ health.
Warca/bazilogon has good stats and stealth
Talo and apollo have good stats and lifeflip self
Galliodragon has lifeflip unlimited
Emeraldeus has camouflage
Shivadragon has hp sharing
Leogeist has life flip self and good stats
Tenebris has foggy entrance and stealth along with having bloodfury taking rexo’s place.
Burnsalot has devour charge
Wraithcaptain has clone, dreamhunt, and dreamy entrance all to keep him alive.
Tridrakhan has survivable stats.
Nightrider has lifeflip self
Lunartic has awesome stats and life flip self
Doomengine has duplicates, shield entrance, and stealth teammate.
Shadowhunter/stormloch has hold ground and dreamhunt
Valsareign has shield entrance and poison drain
Vs
Squishy sweepers:
Rexotyrant
Kamishogun
Midas(situationally a sweeper and has other strengths)
Banedragon(game ender with support)
Goldtail
Shadowyrm
Kamiwyrm
Chromera(has good stats and roaring entrance though to mitigate the frailty.)
Terrordragon(game ender though)
who knows i even use dolphenix
I’m asking this question only because I have Leo,but do you think it will be too much if he get HG?there are good chrono killer in game,seargaurd can’t kill seahowl(it happened all time in PvP) in one shot,but he can kill Leo.im not talking about unlimited life flip,or secret skill for him,only hg. I know he is good sweeper and I think I’m very lucky to have him(saved me a lot of time)but you know, we always wants more 
Sorry if you see this question selfish, but Leo is my only limited leg.

Leo with hold ground would be massively op. He has one of the best passives in the game and if +9 and accelerated and charged up a lot he is doing like half hp to 1 hits on monsters at like 34tu. He needs to be able to be killed quick because if left undealt with then nothing but roaring entrance will come in fast enough to take him out before he can 1 hit you (if charged enough)
That’s what exactly I mean,he needs time to charged up,but most of time he doesn’t have enough.although I know you are right about how he could be,I hope they don’t release another roaring,most of time I can’t even charge him.

“Give hold ground to leo, but legend tks are OP with excessive force” love that logic
It would be too much.
Leogeist is one of the best monsters in the game. For a period of 6 months there was absolutely no stun in the top levels due to the fact that leogeist existed and didn’t have a counter making the shocking entrancers detrimental to your team use. Now we have chrono killer making stun come back due to the fact we can use searguard before the stun.
If we gave him HG then it would go back to the old meta at the top where stun would be detrimental to your team. It would zone an entire 1/3 of all strategies.
Leo is what you would call a situational sweeper. His point is not to sweep but to support. He can sweep, but he doesn’t need to to have a game impact. Like a midasdragon. Midasdragon can sweep, but only situationally when given the opportunity. Otherwise midas’s job is to be a pain with supporting moves like GT, Explosive Quartet, and Death revenge. Leogeist is supposed to sit there and do nothing while he eats all the stuns. If left alone he can sweep, but that is not what people use him for.
Who said not giving exercise force to tks?I want them kill protector/sleep and suggesting new skill for them(combination of sleep/protector plus exercise instead of normal sleep/protector killing, giving them passive will make their AOE a bit too op).
Edit:I’m again sorry if my request made you feel bad,I just got tried when seeing every time sear came in and in less than a min,my Leo is gone.if sear was leg it made sense, but a SE kill leg in less than a min and charging his blood move?!!it a bit bothered me.I hope you understand.
Tnx zard,I know he is good and as I said this request is selfish, but you all someday were like me,had only few legs and game sometimes will get stupidly hard.it comes to us(mostly f2p player)especially when you get valza from rare egg( )and even thinking about this stuff (even if it is called stupid) will make a bit hope in me.
I’m sorry again but sometimes we need a bit motivation

It’s all good 
Yea, i thought u were ones that said excessive force on legend TKs was OP, srry about that
Seriously, that argument on sear is pretty pointless, just use him mid or hide him behind an auto protector who will give u time to kill sear
Tnx both of you and I’ll do that.
F2P Arash
Hide Leo behind 1 auto protector and 1 se protector also pair him with some sweeper monster.
The pain about protector is robin,I faced him a few time,but as zard said all monsters needs weak point and its OK.Leo is pretty good right now
But tnx all
F2P Arash
I want searguard and robin so badly lol
Me too. I joined this game too late to have them and now they are only releasing unharmful monsters as event rewards.
Maybe this new knight will be good if he has hg or some method of healing himself 
Last PVP Robin was a rare sight, common FL were SS and Deo lines. -_-
anyone who questions Leo’s power go and battle lochi and watch yourself get destroyed
If you can stun into it and set up crescendo then it’ll wipe out entire teams.
That being said if you set up terrordragon it’ll do the same thing. Or nightrider. Or even most double attack sweepers. Leo just snowballs much harder then they do once it gets going, the trick is to not let it get up to speed.
