Savages can just use auto attacks specially at higher lvl coz you have a high % of getting AOE on AA. Beside that the main reason I love Savages is due to the totems, the heal one is great, just like predator but the savage one is even better I think. Saves you potions and saves you the trouble of buying hp abso stones from RPs.
Yea I'd say the 75+ for sages is awesome, I guess it's similar to guards althrough guards have less hp abso and no mana abso. But both have a kind of slow start.
