5 months is reaching man. Unless 40-50 is CRAZY slow, a casual player in VG will reach max lvl WAY faster than that. Since the cap is still 40 atm I can only speak to that, but 25% xp an hour is pretty easy to get in the mid 30's. I'd estimate the 10-15 hr a week player will reach the 40's in 3 months, tops. My highest toon atm is 36 and I have 5 alts in the high teens, playing after work 3-4 hours a night, not playing on the weekends. I've been in Beta for..I think 4 months.
Don't believe the hype, VG is not THAT hard. Heh actually alot of people on the VG forums (before they were wiped for B5) were asking leveling to be slowed down, but it doesn't appear it will be. Right now given the massive amount of content it's very easy to outlvl quests and such, forcing people to fight things 3-4 levels below them to complete quests.
It's not EQ1-style grinding by any stretch.
