yea magic missle one does help a lot in the earlier stages, but later on, its damage isn't that good compared to the bigger skills. I guess its almost instant cast is effective if all ur skills are on cooldown @.@ and u can just spam it at just 3mp per shot, its pretty worth it
From the skill master in elderin, there are like lvl 50 skills called fire blast, ice blast or something like that that do more damage than the regular fire bolts. So I am wondering if its still worth it to put any empower points on ice bolt, lightning bolt or fire bolt since their all going to get replaced anyway =\
on a side note, magic burst is definitely worth putting empower points to reduce cool time since its cool time is only 2 secs @.@
