''Second is wrong, beacuse tanks should stand on front line of team and get poke instead of carries. So, unless you are initiating instantly, your passive will be off anyway.''

Disagreed, and here is why:

-needn't be a teamfight (could be, say, a gank or midgame skirmish)

-not all teamfights will have a prolonged poking phase (maybe both teams just happen to be short range with little poke)

-who should be taking poke really heavily depends on the champions in question (Draven doesn't care if he gets hit with an Ezreal Q when he can heal off the damage with one Q of his own)

-nd having Mobi boots lets you dodge said poke more easily anyway (self explanatory)
