Guide Who/What/Where of Joker's wiffs

[StevoSuprem0]

So its not the F2 that whiffs.. I see you talking a lot about the 21 string whiffing on a lot of the cast.... should we not just use F2 the same way superman would use it? Everything can be executed after a F2 (OH, teeth, RLG, acid). Is it too punishable to be used?

Well if you are fighting someone with the whiff issues, just use 32. Alot more damage, no whiff issues anywhere, and super easy to hit confirm into.
F2 is a lot easier to punish if you try to trick them with a teeth setup and can't be hitconfirmed so you are constantly having to guess whether they're gonna get hit by something. As a punish, it's an ok option, but I'd probably go with 11 instead in punish situations because its faster.
21 just gives a lot of frametrap and setup options, so it's a shame that it doesn't work on a lot of characters.
