The changes will be minimal, although necessary.
I agree.
In terms of the balance and meta, the game appears to be in a great state, as observed by the tournament in Mexico and Austria.
Nonetheless, I would like to see some buffs for the lesser used characters/kameos like Peacemaker, Tanya, and Stryker.
Because Peacemaker's d,b+4 has more recovery frames on block now, the cool down should be reduced.
Tanya needs more perks after charging Seeking Guidance (d,f+3). On a full charge, the armor, EX d/b+4, should be safe on block but not launch with any kameo, as a contrast to Kung Lao. The fully charged ground and aerial fireball should have an extra perk as well.
While nobody wants the old grenade meta back, Stryker is one of the few bad kameos in this game. NRS should explore buffing Kuffed and/or implementing a new attack.
Reverse the Reiko throwing star nerf; have it trade.
NRS is historically really stubborn about reversing/reverting changes.
If Reiko is supposed to be a command grab character, EX pale rider should cost one bar instead of two.
EX stars should also arguably be better in a way since you are spending a bar.
Considering these two changes alone, I do believe that players would actually use this character.
