Is chantodo set mandatory?

can we replace chantodo set with (gesture of orpheus with 20fire skill% + firebird offhand(20% fire dmg)

this allow us to equip magefist gloves with 20% fire dmg.

so my point is chantodo vs 60% fire dmg??

Not even remotely close. Did you not read the Chantodo's set bonus?

if i am right with 20stacks it deal 7000% weapon dmg every sec? or it provide more?

7000% every second while in Archon, and it's elemental so gets multiplied like any other skill.

just think that that 1.6x on some high crit is more important then that pulsing dmg, have some feeling that it doesnt do any dmg to mobs
but guess since all people prolly is better just had an idea

This would not work, chantodos is very important... just try it and you will see

Or even try NOT STACKING chantodos and see if you still kill the same elite in the same time

It is mandatory as it provide good burst which synergizes with coe very well. 7000% during archon is a lot more than additional 60% constant.
