Riot, can you please address Tryndamere's balance state?

First point I'd like to address. We all know what's so frustrating about Tryndamere, right? That five seconds of invincibility...just doesn't really seem to fit the definition of the word 'balanced', does it?

Especially now with the new masteries being introduced, Tryndamere is absolutely devastating. Free critical strikes, mobility (which gets a lowered CD when he crits), and five seconds of invincibility.

With the introduction of the 'Warlord's Bloodlust' mastery, Tryndamere not only benefits even MORE from critical strikes, he's healing more from both his Q AND his passively gained critical chance.

Really, you could be attacking him under tower when he's splitpushing, and he'll shrug off the attacks and destroy whatever objective he's trying for, then E away like absolutely nothing happened. Plus, last game, I witnessed a Tryndamere soloing baron, by himself. Taking absolutely ZERO damage. Is this, really your definition of a healthy champion?

So please, Riot. Just take a quick look at him, do something to make him manageable in lane, teamfights, and just in plain general the game entirely.
