Wow, the XP bonus in HOT zones is pretty phenomenal. I wonder if they upped it in recent months since I don't remember it being so good.
I was foolin' around making a new toon on Stromm, for kicks, and at 35 my warrior can get 20% of AN ENTIRE LEVEL'S XP from soloing one yellow. That's in The Overthere. Even dark blue mobs give 8-9% regular XP. Soloing a yellow isn't that tough with decent gear and especially potions (yum damage shields.)
That's almost TOO fast since you can fly through the 20s and 30s---5 kills per level is too fast, methinks. This is better than WoW's Refer-a-Friend triple XP bonus and WoW gets criticized for making things too easy.
And this is without using LoTD or Adventure potions.
I'm not really complaining just wondering what others think about this fast an XP pace. I actually made a new toon just to re-experience the "original" game and the Old World zones but the "drive to level" is so strong that I'm rapidly running through the ole zones...
