No, it isnt. Because u lose dps that actually lands. Are u that stupid or what? So with 1 attack u would still go for it?
Like I have said before, it is a weapon change, NOT a build change. If something is 900 dmg and 2000 attack and something is 40 dmg and 2000 attack, what would you choose? And it's not hurting dps as your solely doing it in downtime.
It is hurting your dps and this is why:
Due to the availibility of cooldown items, you no longer have to wait that long for cooldowns. In this short amount of time it's best to cast your buffs like eshield/lures.
What you propose is to swap alot pf gear within 2-3 seconds to do an auto atack. The dl wand has an attack speed of 3000, what means that it does damage every 3 seconds. So you can only do one auto between your skill hits. Due to your low attack, the chance that that auto actually lands is very low. And when it does it only deals 400 damage max if you have good damage gear.
So you have just done one auto before you have to swap your gear back. You have to delay your skill cast, because you were trying to do one auto. Every second that you delay your dps skill cast as a mage is a loss in dps. And autos cant make up for that.
