This is a fairly common argument I hear people using to say something should be high in the tier list, so you canât ignore it 
Shiny Cyclozar is basically the modern version of it. Iâd argue Chromera was never really that good anyway, it had a niche in the meta for a while after it came out then was drastically power crept out the following year but it saw play for much longer after because people overrated roaring entrance.
Changing bloodthirst into bloodfury (as it was originally intended to be) would be a cool upgrade that definitely wouldnât be overpowered these days.
I know this quote is for something a little different, but earlier you were trying to bring up monsters you never see in PvP and say therefore they should be buffed.
Here are mythics I practically never see:
Focalforce, Mistletorment, Aethereon, Scyberithe, Cypridrus, Ankara, Rodeknight, Mechydra, Onika, Mai, Majorie, Hawknight, Atlanachia, Akane
And ones I see extremely rarely (every 500+ hundred games):
Deviladus, Brynhildr, Yukihime, Gorgodrake, Uraniumedhus, Kunomi, Medbie, Fiona, Noircyon, Coretta, Hu Shin, Orochi, Goliatherion, Vespia
Extremely rarely but common in past:
Gremoris, Kanna, Lime, Ophidiator, Apollonis
^ I excluded ones that came out in the last year, because many of them are âextremely rareâ so far.
Out of all these, picking Noircyon which is restricted to link (therefore naturally will see less play) and Lime which used to be common are slightly odd picks I think. Some of these I listed are brilliant monsters, so not seeing much play doesnât necessarily mean it needs a buff.
I think itâs also pretty obvious from that how there are a lot of mythics which are rarely used. If we tried to buff them all to become commonly used weâd end up with huge power creep.
