They have great dps and survival, and can dominate in pvp. A healer can heal all they want, but their hps can't outdo dps, they're screwed. Especially since many classes have crowd control ability. The other reason I pick illusionist over templar warriors is because great heroes are great but fallen angel and illusion angel have more advantages. But Great Heroes are my 2nd, and pretty much tied with machine gun bounty hunters...especially dragon slayers. Matter in fact, I would say all 3 are a tie for me But since I'm an Illusionist, I'm voted for my flock.
illus ar the best when it comes to soloing....thy ar realy cheap to.....but sorry to say...if u dont have enuf leech ans ias u get raped by the lvl 65 skil of great hero ( worrior ) ans tangle strangle skill ( archer )
