Good job doing that underussed skills or builds get more use with 2.4, but guys you missed some important things:
Amazon Multiple Shot: Nearly no one is using it. Please, remove the 1/4 damage reduction like you did in Strafe. Now multiple shot amazons are extremely unused and everyone is using strafe or other skills. You improved strafe but forgot to improve multiple shot. Also, only two of the arrows get adds from crushing blow, knockback, etc… please solve that, every arrow must get the adds (like in strafe) to make this skill again used. Another possible correction will be reduce mana use. Then, using multiple shot amazon will be again enjoyable in all difficulties.
Amazon Immolation Arrow: No one is using it, and probably no one will use it with your minor changes. Please, remove or reduce the casting delay, it is too much high.
Please, reconsider adding these changes, those skills are very wonderful but extremely underused now.
