Riot can you just fucking look at Tryndamere???
He is just so easily kited it's a pain to play him when the enemy has as much as a slow. He needs changes to help him combat those ranged adcs and kiting in general...
Ideas:
Mocking Shout: Tryndamere becomes immune to slows for the duration.
Undying Rage: Tryndamere receives 30/50/70% tenacity for the duration.
With these changes he will at least be able to stick to his target, thanks for reading.
Activate it to remove all debuffs and provide some move speed to catch your squishy opponent. (90 sec cooldown) :) HAVE FUN!
