These PBE Tryndamere buff is actually not a buff

Tryndamere Undying Rage (R) - while R is active, Tryndamere can now not be reduced below 30/50/70 HP up from 1 HP

His current R heals him back to 3% max health at the end of duration anyway, with his base HP at level 18 it heals him 69 HP. 69 + 1 = 70 Same goes at level 6/11 And some Trynd player doesn't even level his ult to rank 2 until level 17, this change just forced everyone not to do that now. Tada...

So if Tryndamere grab some bonus health (from runes, masteries, etc.) this is actually a nerf.
