and obviously spamming is slowing things down if you dished out all you could and wound up left empty for the next 10 seconds or so. and i'm pretty sure you know how much damage can be dealt in 10 seconds.
specifics? it's pretty obvious, 4 piece elf hero for 50% more dmg and mana regen and 3+1 GT to name one.
yeah, dacy does more burst damage, but can easily be beat by most other classes in dps, if you know how to manage your mana, and if you're worried about incinvibility in ghost raid...then have fun in bonus.
but as always, spammers will be spammers.
or, a easy solution, go back to dacy.
