LM has the strongest immunity out of all the mains, wind with dance of impetus can remove all debuffs for 1 time (and they can be reapplied ) or have ONLY female 2 ninjas immune for 2 rounds, earth main is even worse where he removes only 1 stack of debuffs and doesn't make anyone immune, firemain only does it for 1 turn and has to be manually applied. Lightning main on the other hand just makes all the sword users immune for 2 rounds not to mention that his calm mind makes him immune for all game (if you can get it off b4 u get disabled).

So i don't see a reason LM should have any more debuff clearing abilities (unless they replace root of warrior altogether)
