A lich requires a quest and a bunch of immortal backers, also many quality characters for said lich quest to even be given to that player, then find or not find the items..

To be a poisoner/trapper, you could have 100 quality characters, you are going to still have to invest insane time and then constant many ingame hours for resupplying, every other day or DAILY, i.e. PREP just to be able to do anything.

A poisoner/trapper is a different level altogether for the initial grind for skills, ingredients, traps and then non-stop gold grinding, resupplying. Run out of gold because you're being flyto/pecked every moment or stalked by people who see you? Too bad, you become useless.

I've played every class ingame, except a lich and a Vampyre, I know what I'm talking about.
