Aatrox and the new masteries
Honestly, I haven't played since they released all of this, but I am excited to. Here is why:
1)Battle Trance favors Aatrox--he will be in combat for 5 seconds trading blows or chasing, with his sustain, so he will often get the maximum benefit
2)Fresh blood provides extra damage in a category where the other 2 masteries are really no good on him
3)Fervor of Battle ads bonus AD. Well, this is much better than the on-hit damage that it used to be, relative to the fact that opposing champions may not benefit as much as he does with the new mastery--Aatrox scales at 100% bonus AD with Blood Price, and moderately with Blood Thirst...you may not think its a lot but that 60 AD translates into 15 health when using Blood Thirst, but when he is under 50% health that is an extra 45 health on top of whatever else he normally would have gotten, at level 18, not including the increase from Runic Armor Mastery or Spirit Visage. This will make a mid level Aatrox at around level 12 healing at 200 health per Blood Thirst hit heal at 232 or so That is a pretty big increase, its the same as having one extra item that gives 42 AD (What he bonus would be at level 12 with full stacks)
