1) He most likely had no idea the server population would be bad when he rolled, non of us had any idea on how populated they would be.
2) If he started during early access, it's now been 6 weeks since release, not exactly speed leveling
3) Just because we was a 50 in a zone against level 10s doesn't mean that's why we played it. If you notice he asks to expand it to 40, not level 10. Right now some servers have no WZ action. Such as mine, I only ever get Huttball and even if I'm lucky enough to fight something non-Huttball we end up with at least 2 AFK players.
Thank fully I don't mind PvE so I have gone back to tank spec and decided to reinstall Guild Wars for my PvP. However once I have done the PvE content a few times I don't see myself resubbing unless they keep releasing top quality content as I am a PvP player at heart.
