I'll let you in on a little secret. I play a tamer mage. My main character is a tamer first, a character that relies on pets for primary offensive capabilities.
Yeah me too. In fact she's my only character (siege). I have access to a sampire on friends account, but I don't use him. I've been a tamer mage since 98.
I'll admit I don't do peerless, etc, cause I don't like the stress of soloing such things, and I'm aware that many of the peerless are too hard to solo with a tamer, but I have done everything else solo, and most of the time all I do is stand off and and heal. If the pet gets too hurt, I run a screen off, log in and out, heal it up, and go back to it no problem. I'm quite sure there are peerless and other boss level guys I could solo, I'm just too lazy to try.
90% of the situations I can just take my GD, and sick it on whatever and...stand off and heal with aids, or in danger of area attack, with Magery. My gear is pretty low level usually, usually some luck + some MR, some + int... nothing that requires anything other than regular gems and residue, never all 70's resist, rarely any resit at 70.
2 Tamers with GD should be able to take down almost anything, except the Stygian Dragon, and the Slasher of Viels, with little danger.
The odd occasions I do play the sampire, he HAS to have certain gear, and HAS to have all 70's suit, which for a lazy butt like me is usually too much trouble. Tamer is pretty much all grab and go, and I'm ready for most of the game solo.
