How much do you do to earn it though? You get a lot of it from just taking damage and doing stuff that you would normally do. I think mostly, it encouraged you to throw more projectiles, which isn't necessarily a bad thing, but I don't know if it was really that deep outside of zoning wars.Meter doesnt recharge for free in those games.
I know you can make a case for these characters having mad meterbuild but still had to be earned.
Also, if we're talking about character discrepancies, the meter build mechanics of MK9, IGAU, MKX and INJ2 all contributed to bad matchups and was an inconsistent mechanic across different characters. I know you mentioned the mad meterbuild some characters had but I'd say it's one of the biggest issues they had with balance across the games. There was too many Brainiacs vs Batman, Bo' Rai Chos vs Mileena, Kabals vs the world, etc. Though obviously, other games have meter build systems so it's not like it can't work.
On the other hand, I feel that my lower damage character can compete much more because of the existence of breakaway and how his damage is largely unbreakable.
