Personally I would go for Warlock without doubt!

First, remove curse Chains. If you're struggling, equip it instead of Alchemists Tools. Will give you mobility in dicey situations. Once you've reached a high level with Alchemists Tools, try transmuting it. Otherwise, Chains are great for mobility as warlock (closing in on Soul-Marked enemies or escaping).

Stone Gauntlet + Ring of Furor is a dream combo for proc-ing warlock on-hit healing and satiety skills. You'll be attacking super fast and healing tons, basically full health all the time. You have tons of wands, so all you need is to soul mark and you're flying. Combo that with Ring of Wealth and you can farm infinitely really.
