Two things to completely deny Tahm for those of you calling him op

with the Alacrity enchantment And two points into the defense tree : Swiftness for 15% slow resistance

And if everyone buys these boots (and the two points) there goes most of Tahm's offense and his only real way to get to you 1v1 is wasting his ult, and for teamfights, well just back away from him once you get two stacks
