you can not back dash when you are in the corner and while like any characters there are gaps that dosn't mean that the pressure is insane. The difference is the damage you take while IN the pressure. Take A-List... probably the current top pressure character in the corner. I mean you hit block and it is just not your turn for ages. Acidic is not as bad as that pressure wise, but because the damage happens through a DoT even on block makes Flame Fist Kang or Caltops Black damage on block look trivial.
I can not see who anyone can defend the idea that getting hit by a block string and loosing nearly 40% life can not be considered a little much. Blocking shouldn't work that way and dosn't work that way for anyone else in the cast.
there is plenty more options than backdash, armor and it removes all dot stack. if you noticed that when you armor right when they use DB2 or DB4 the Dot damage does not apply when it hits armor. so there is plenty options, and if you are worried about chip and dot so much, you should meter manage and use it for negating there damage.
personally i have no problems with Acidic, thats probably because i used acidic before the nerf, but after the nerf to game point with dot, i dropped it, because that is what was fun for me.
and Acidic lost vortex off EX DB4 which is kinda bs because so many characters get to keep the vortex.
but no matter because my main was Cyrax, and im gonna stick with him no matter.
people thought he was uber op, and he was not. his neutral was garbage, many strings where unsafe. bombs are unsafe, net is unsafe.
besides his reset. but everything he did was only if you let him open up, so in other words you made a mistake and let him get you open, or didn't punish a negative string, and let him follow up. or a negative bomb set. my god they are 106 on startup and negative 73 on recovery.
there was actually people stating his EX bombs where op because they where Plus 8, and they where not, the game stated they where but they where like -7
i just feel the majority of the community nerfs first and never labs.
most of the so called tools that most characters have are very much defendable. you just need to learn the matchup.
if everyone got there requests then this game will turn to garbage.
