Tryndamere + New Crit Keystone Mastery = Ticking Balance Timebomb
Warlord's Bloodlust: Moderate lifesteal upon crit with 2-sec cooldown. Tryndamere: Up to 35% crit chance without items + Q bloodlust heal.
There are only 3 possible outcomes.
- Trynd becomes immovable object in lane.
- Crit Keystone Mastery is weak, balanced for Trynd but useless for most other champions.
- Tryndamere nerfed :/
Either way, 
effectively becomes pigeon-holed into taking this one mastery which equals less diversity.
Suggestion: Replace Warlord's Bloodlust with more universal on-attack heal that scales off total AD/AP rather than crit. Also gives AP champions a second option in Ferocity tree which equals more diversity.
(All arguments may also apply to 
as well)
