my character is a summoner.. with summon/necro/poly.. and its pretty amazing..
at max rank summoning the pet is a giant behemoth of destruction capable of holding its own in any fight.. along with my necromancy to attack them directly after my pet rips thru their armor like its butter.. with my poly i took spread wings cloak(in case the enemy tries to focus me down i can invis and let my much tankier pet handle things) heart of steel.. also took medusa head because i found the skillbook laying around and its actually quite good.. because now i can cc.harm them whether they have physical or magic armor.
my setup managed to 3 vs 1 my team in the arena where we were all forced to fight each other and won.. despite 1 being an assassin with stealth and backstab.. it didnt matter cus my pet shattered his armor then i kept him cced the rest of the fight.. they ended up calling my summoner OP..
they realized i was the greatest threat and even with them all teaming up against me.. they stood no chance against me and my pet... i know this isnt really related.. but it felt awsome to me to single handedly wipe my own team.
