... why does every cry for help end up in an insultfest between you guys? Seriously, if you want to measure your egos, go into the game and pvp...
Junebabe, all you had to do was ask for advice lol. Generally, for pve, vampire summoners have higher survivability and drastically higher solo ability, while acid builds have much higher dps.
This is the build I used to run with before switching out to acid for a while for the a4 dps.

And yes noob, before you snort at soloing, do tell, how do you imagine financing stuff now that economy nerfs came in? Without sinking a [I Have a Potty Mouth] of cash into gpots anyway.
The ideal, however, is to get the Title of the Great, and just switch between Acid and Vamp at will

see ya in 11 weeks.
