I keep going between the two, haven't made it past act 1 because I can't decide.

I dont want two games on the go at once. For Ranger it would be a Hunter, focusing on Archery and special arrows.
Warlock would be Fiend, pact of tome focusing on spells and Eldritch Blast.

Character would be a Drow.

I also think I'm allergic to multiclassing.... I've never done it in any game I've played. Don't like the thought of giving up higher level feats for low level feats from another class.... what benefits would I get from multiclassing, I've read about sorlocks....

Any advice on what to do?
