Nope, not a troll post or anything. ARPGs are one of my favorite type games. Just having one skill you use is getting boring already.
I didn't think it was a troll post, to be honest. I've just been on GameFAQs long enough to know how the boards work (or don't work sometimes).
You're right in saying that the one-skill element can get repetitive, but Gearbox did such an excellent job making Borderlands a loot-driven game that it works well. The classes all feel distinct too, which makes switching among them really enjoyable.
You never know what's going to come next. Enjoy life and let God take care of the rest!
