No idea if this is a bug or something overlooked or if it's supposed to be this way.. (Playing on normal difficulty, level four.) Exploring above Primm I came across a Ghoul Reaver stuck in a rock.. good.. he can't kill me. So I lob about 10 grenades , 4 dynamite sticks and a couple rounds from the varmant rifle to bring him down. (tough to bring down) 50xp... I keep exploring and come across a bunch of Ghoul Roamers.. takes about 5 shots with the varmant rifle to kill each of them.. Each of them nets 50xp each... Huh? I level to 5 from killing Ghoul Roamers. That just seems like way too much xp for pink fleshy roamers with no armor.
I really hope this is a bug because so far the xp has seemed pretty good for creatures. I really don't want to level up that fast. It's annoying to get halfway through a game and have no more leveling to look forward to.
