It doesn't add depth, it adds the ability for someone that should take extra damage, to get up, ignore the damage, and punish adequately to where this should be removed. I've been able to do this with like a 5% frequency using the combo in the video on page one. Yes it is very hard but with enough practice and knowledge, someone might be able to do it consistently enough to where you simply cant tech trap them, and they get to punish you every time because they got to JG your tech trap. Everyone who says "it adds depth", i'd like to see fight an opponent who can do this frequently, and see what kind of depth that would add.
TL;DR Patch this crap out.
