I realy cant choose between some buffs tell my your way to buff AW
i know for sure - champ/rene/cov ...
I want to know that AW need focus and hunter or not?

I dunno but for mi i will get song renewal, hunter, warding, earth, vitality and champ .. Dance of fire, warrior and fury.. And DC buff with CoV/PoW

u talk about oly?nah ur skills do the job and u dont need that!so imo ur five buffs should be
1WW
2song of wind
3champion
4haste(for reuse of ur skills again)/shield
5Pow

yeah the shield is missing but imo this way u r very very fast moving nigga
+u have prety nice reuse of ur skills:D but u r made of glass:D
no btb=lower hp no shield=archers like ur back on the ground no magic barrier=mages love u no resistance=same
but anyway all enemyes are different and u need different buffs
