First bronzeshells ruin your opponent stratgey which already gives him a huge disadvantage second they require around 180 to to get rid off third they are not stun immune how much more disadvantge you have to give the other player.
My suggestion is.
No 
they have accelerate team they strong enough
Newbies. Have you heared of motor unwanted enterance or you still havent played aganist one yet.
That would be an indirect nerf to motor. If you have two shells (motor passive) on the ground stunned to hell (that is a common strategy in pvp right now), you are pretty much done.
Btw i like first idea, not the second one cause they’ll never get a chance to kill themselves
Understand the game mechanics, then come back and try again
Like the idea of the stunn immune shells though 
Motor and Shocking entrance combo is just too powerful.
I would rather shells be added to my team than boxes. Shells can at least kill themselves without damaging your team and sometimes the accelerate team actually comes in handy. The boxes are stunable aswell, they offer no utility and the only way to get rid of them is by blowing up which does a stupid amount of damage. It puts holy legends to half hp. If your on hold ground then you killed off your own team which messes you up. And Midas gives you 4 of them
Making motors shell stun immune would be fine. That sounds fair to me but in exchange they should make his knockback next less TU
I love to mess up the enemy team with lunartic and stun immune shells would be a hard nerf for him - more than for motor. But I have to admit it would be just fair. Two stunned shells on the field and the game is over… and extremely boring for the victim… besides of the point that it kills every dynamic gameplay.
Btw… this suggestion (1) has already been made many months ago… if they keep their development speed they might be able to implement this in maybe 3 years or so.
I honestly think if the shells get stun immune then the boxes should too. The meta is very much trending towards stun and disruption and I think that the boxes/shells themselves are disrupting enough without it being possible to stun them for a ridiculous amount.
How about a 400sec bomb for the shells that goes automatically of after 400secs. The damage wouldn’t be really high of course but at least the mons on HG would die if the shells are not taken out timely
400 secs is way more than enough time to kill a team.
Depends on the team and would be more fair than it is atm, but ok lets say 100 sec bomb then, it would accelerate and go off, sounds great
I like the idea of the bronzeshell having a 200 or 250 bomb. It does little damage and goes off automatically. That sounds like a good idea. I do agree buck also that the boxes should be stun immune if bronze shell get bomb or stun immune. But then that completely ruins tinker. His whole move set is set on stunning the boxes then survivor. It would ruin him. They could just have a passive disintegrate. Where after 250 they auto die. I like that the best. Like I said though if they do something with the shells they need to give him a secret skill or reduced TU on knockback next
give bronzecell autoprotect that will solve all problems here
That is actually a pretty great idea. That means that they will be used as intended- motor food. Rather then an instant win button.
that would be a perfect idea, the only problem i see is it will literally buff robin and icefang
2 bronzeshells = assassinate completely blocked
hahaha but UC will be extremely challenging 
1 = suicide lol.
But seriously its a 60% to block sooo
Auto protect could work.
