I've played KL HT for over two years, and even though the Hatrick development was not complete, I was still able to maintain my grounds, and that was because his core moves were solid.
In world of MK11, he lacks them in both variation.
f1 is useless because you cant confirm of off it - if that would change, we could be able to make use of it.
There has to be a move to condition opponent to block high. The design KL and JC had in MKX was decent and fair.
Even if f12 will be an overhead, decent player will still poke out of 21212 string and wont force them to block high. In that case the b3 and all over high strings, pokes wont be effective.
The string f23 could be around -8 /-10, since -13 is just considering what others have.
The teleport: day one everyone I played in offline game was able to AA me with S1.
The character is fun. Has mobility, sort of anti zoning, but in order to land combo, you need a moron, or realy on whiff punish, or AA.
The way Foxy played T Master, is a good example, how bad his overall move set is.
