So what's the problem if Yasuo's double-crit passive is removed?

I mean this type of change can definitely harm his Tank builds a lot, considering the fact that he only needs a Phantom Dancer to touch 60% crits while building the rest of his kits with Tank Items & Bloodthirster.

Another reason would be that it doesn't seem to make a point of why having 90% or 100% crit is necessary at all. Majority of Yasuo players tends to rush a straight Infinite Edge & Phantom Dancer to achieve the 90% crit mark. As long as he has both of these core items, he can proceed to build heavy HP items like Frozen Mallet or Randuin's Omen & became resistance af (especially if he also builds Bloodthirster or uses the Warlord's Bloodlust keystone). Take away the double-crit passive, having both items will still achieve him a 50% crit mark whilst having the ability to be highly mobile, which imo is more than enough.

I would prefer if his double-crit passive is removed, while compensate it by having his Q damage upped a little.
