riven keystone masterie

deathfire touch or fevour of battle? fevour of battle gives early game at 10 stacks 10 bonus dmg and at lategame 80 on auto attacks but wich riven doesnt need since she has a passive dat does dat job.... deathfire touch is something dat doesnt need stack... it just burns the enemy with your q or your w spells also with ultimate... it feels like rivens old q dmg is back since season 3 riven q dmg was nerfed early game but with this masterie.. riven q deals like season 3 riven q... it feels so and dont forget dat it turns bonus ad into magie dmg wich is quit op cause enemy will not buy magie resi against riven... wich i really love dat it turns ad dmg into magie dmg.. i know it applies half of the dmg cause riven is aoe but insteed of 3 sec.. it applies in 1,5 sec so wich is almost the same.... i like deathfire touch since it deals magie dmg and counters armor and makes the q dmg stronger like in season 3... and if i take fevour of battle.. then i have almost the same again like my passive do.. wich is boring
