So I hit 45 last night and went to town and got my stuff squared away. Then joined the IA which I kept hearing about. The first place I was teleported to had joint Guardian & Defiant killings things and well, like an old raider told me once "Tab targeting is of the devil". I didn't realize I had targeted a flagged Defiant and hit my attack button before I could realize it. Yup, you guessed it..... Some other level 50 wiped his but with my head pretty quickly.
The XP just fly's by and within an hour I dinged 46. I still have my XP pot and am gonna use it when I have a straight 2 hours to play. But "My God" people weren't kidding when they said the levels 45~50 will fly by compared to the last 5.
Anyways, hat's off to Rift for the IA and it is nice to be able to jump in to an instant "I want to kill shit" group.
