Tryndamere Is Awful
Tryndamere is only good if you get 

and have your ult and not get cc'd. He needs to get buffed. He could get buffed by adding a new passive on his e: Reduce 1 second off of Spinning Slash (e) each time he gets slow and reduce 1.5 - 2 seconds for each time he gets stunned. Reduce .5 second whenever Tryndamere critically strikes.
