Okay, I don't play FR, so I only the basic concept of what swordmages do. So can you explain how a swordmage can hit and kill 12-16 minions in 2 rounds with At-Wills? A regular Wizard couldn't even do that with Scorching Burst unless he had a godly hit stat and they were packed like sardines.
It is not JUST the killing... he is just MORE adept at it, and the party suffers nothing for it. He swings at a real mob, adn auto-hits ANY adjacent enemy, which kills any of the minions around the real mob (hence the staggering I mentioned), it is MUCH more powerful than cleave, so yes, Swordmage is overpowered, plus if the SM has an ally adj to the mob, it doesn't hurt the ally lol...
but between a ranger (twin-strike), a rogue, a Fighter, SwordMage, Cleric, Warlord, they manage to kill around 8-12 minions per round... so I have to send in waves if I wanna even use minions, unless I put the minions in the back and have nothing but blockades of real mobs up front...
