Nah only the ignorant would complain about it unless SE made the rested xp with overpowered gains. In WoW the rested xp just allowed someone to get back within range of a dedicated leveler. However the dedicated person would still be ahead with gear, enchants, and etc.
The surplus system is really annoying though. I have a lot of fun until I hit it then I get really bored. Leveling other jobs does not make it replenish fast enough(if it does at all). So in the end I have to wait a week... Why the hell is my character so lazy it takes a week for him to get his strength back?
