There shouldn't have been a misunderstanding. Seems like he just jumped to conclusions before comprehending what he read. I read over what you said 10 different times to see if there was any possible way to misunderstand what you were trying to say. End result: There was nothing to misunderstand.
Agreed, it was obvious that the safety was in regards to Shaolin, and then he offered Bojutsu as another simple execution character as a separate thought.
As for the OP, I think slasher Jason is incredibly easy execution-wise. The links for the low stomp string (haven't played him in a long while, forgive me forgetting the inputs) to loop, and then for the ender, or the b112 or whatever into an ender are so fucking forgiving, you can basically hit them at any height in the juggle and it still connects. To me, easiest combos I've done in the game. I always hear that Jin is a great character for new players, and I'd say the same for Jason given his improved pokes.
I've played Kotal for a total of an hour ever, but in five minutes, I was stumbling upon the bnb's I see high level players doing....I'm not saying it's easy to play Kotal at a high. competitive level, but the actual inputs are ezpz, and the fact that you pretty much make em guess on the ender means as a new player it doesn't take a ton to land some damage.
