All GF+BTB skolvers with 2x 5* heart trinkets. Make this a default set given to everyone in lockdown and no more balance issues. Oh, and let people buy themselves UV bonuses with CE so you dont lose income. No more whining about imbalance. Brilliant, eh?
Oh, and give bombers and gunners sets too but dont change the stats so nobody will use them anyways unless they're hipsters or idiots
How'd you know they have 2x penta hearths? Since you cant see the entire lifebars, 2x pentas have the same visual effect as 2x tetra hearths or any other combination.
