I disagree. I cannot build nearly enough Resources with Chains as with Sun Burst. For my build there is no way around it. Im almost constantly using Forgemasters and AS both cast with divinity and Sun Burst does a lot to help me recharge. Mostly I disagree with the Kickback - its very very useful - not just kicking back…
I agree, Sun Burst is generating a whole lot of Resources - +the other mentioned advantages. And the knockback is just too useful for capping and kicking other people out of an Enemy Astral shield. You can chain them - but what good is it going to do if you chain them on 1 or even 2 AS?
