why are people still upset about the armor system, its just a casual filter.
im still in favor of 6 p party
Not sure what you mean with "casual filter", but itìs because it was a flawed mechanic that introduced way more issues than the ones it tried to solve.
It was a dumb system that:
1. Forced people to focus on one single damage type to not lose effectiveness.
2- Favored damage above anything else-
3- Made the fight completely binary, with a first phase where any form of crowd control was completely useless (until you bypassed an armor) and a second one where it was completely unavoidable since it worked 100% of the times.
It was also a very poor approximation of how an armor is supposed to work at mitigating damage in reality, if we want to take that angle.
XCOM 2, to name one, came with a far simpler, less convoluted and more interesting mechanic to simulate armor.
