Any amount of time is a pain in the ass, and its 10 hours if you happen to know the absolute best locations and have ppu support the whole time (or know some exploits). Either way thats 10 hours of boredom I'd rather never suffer, since we lost all our character I've only had 1 capped char, I did my time in the salt mines of leveling characters, and I'm never going back!! I've got to many mental scares from hours of boring grinding while being ganked constantly in places that take 30 minutes to get back to (not including SI and reimping time)....
Seriously F pve in this game F it to holy hell, please PLEASE can one of the devs confirm that they are working on making it not worse than working in a salt mine wearing a suit of razor that point inward, I want to play more than 1 character but seriously I can't suffer through that crap ever again.
