After playing the newer gen of these games, its easy to understand that the level of input latency is high due to the fact that they are 3d games with a high frame count(dynamics, event functions of the background, etc). There may be mixups and situational tactics you are going to have to lay off on since they require execution not available online, or it just may be the character that you are using who has tactics that can be deemed unsafe.
Are high-execution characters, faster attacking character bad for use online? In an example, like UMvC3, it’s not every day you’ll spot a C.V, or M.O.D.O.K, due to their pressure/cancel/ zoning options. Simple BnBs don’t do solid damage, and with any luck, you’ll skim past the 500,000 dmg mark with an assist you’ll have to rely on. You’ll have to work around the lag to feel comfortable with matchups you know
What characters have been not too good on the side of online latency? Name the series, and the reason if you could.
