Can Riot fix Tryndamere, Please? He has a BUG BUG BUG

I play jungle Tryndamere basically every game. But, unfortunately, he is absolutely broken now. Smite kills Tryndamere while he's in undying rage. Is this supposed to happen? If the enemy jungler smites me while I'm in undying rage, I die immediately. Sort of renders Tryndamere completely worthless. So how about you fix him for me :). But, don't take 12+ hours to do it? <3

Thanks.
