I'm sorry to tell you, but traders are quite strong enough. Let's see... root, pacify, drain, wrangler, AC drain, grid spells, and lifetaps/heals?
Now I admit, many of those lines are less than spectacular. But you can use a crit-shotgun QL 200 EARLY on (50-60 if you're really good), get into a low-light scope for critbuff, and keep up both drains, effectively increasing skill large amounts (300pts or so easily by level 100), which in turn increases damage output/hit rate. I've heard that the damage output formula is 25% * skill/33 * weapon base damage. According to that, an extra 300 points from drains means doing about... 3x3x25... what is that, 175% base weapon damage? Yeah, definately weak, especially when crit-shotguns are the best weapon in the game :/
