Haha! Nice Game. Played it throughout my college life and I still play sometimes if I get time. But beware it is very addicting.
The classiest way to play sniper, farm dragon lance and Mjollnir, stay behind your teammates and shoot the shit out of the enemy. Upgrade the dragon lance for Hurricane pike as it also works like a force staff . Keep building damage throughout and most importantly, keep an eye out for the occasional blademail. :)
