Mercury's treads tenacity & magic resist
Is there any reason, that, when i have to buy tenacity in this game, from the ONLY item that gives me that, i also buy magic resist, even though i don't really need it (eg. full AD enemy team) ?
It's exactly the case of jungle enchantement... Play a manaless jungler, and you are obliged to buy a mana regen item which is TOTALLY useless on you.
Why ?
