well incinerate has higher scaling,higher base damage, same range and its aoe so imo its quite alot better than disintegrate. i suppose disintegrate gives more sustained damage but thats not really what annies made for ^^

Just personal preference, you can max incinerate if thats what you're used to. I just don't like the animation of incinerate because I feel like its a really short range.

Another great guide, I've always love your guides :p
May I ask why do you max Disintegrate first rather than Incinerate? They both have the same range and Incinerate is AoE.
