True, a 1s stun is 20% of your ult wasted, but 35 Tenacity gets only 7 of that 20% back. At 2.5 attacks per second (maxed), that is still about one autoattck only. Also, Zerkers cost 3/4 of the amount of Merc Treads, and will allow you to finish the items with more pop a bit quicker. There are advantages and disadvantages, but It's not an open-and-shut case.
