Hey, I wanted to say that I build a wierd fighter/bard/rogue deep gnome or something mix that was int based and ran color spray, birst of glacial wrath, and dire charge.
I didn’t have a bunch of past lives and my gear and feats where not optimal but it was rather fun to run in elite/EE questing. I found that at cap it didn’t work as well as a more streamlined toon. It failed somewhat hard in epic reaper questing. I may try something similar with a better toon, both gear and build.
But i wanted to say a build like this can and will work. One of the advantages of going charisma/int is you can twist in energy burst to.
