Long time WOW player, just recently came back to Rift.
Amazed really at how good and FUN the leveling experience is in Rift. I feel no need to rush and there are just so many things to do that it never feels like a grind.
One thing I like especially is the epic story line quests. They remind me of the epic and class questlines form WOW like Onyxia (which I have no idea why they removed) and really give a great feeling of accomplishment.
Throw in huge questing areas, artifacts!!, instant adventures, rifts, invasions and rift events, and SIGNIFICANTLY better low level dungeons it is just a fantastic experience.
WOW us still like a comfortable shoe you like wearing and I will always play it I think, but the PVE experience in Rift, especially leveling is just at a different level than WOW.
The only mis-step I think are the starting areas which are bland and unintersting, an area that WOW is far ahead of RIFT in.
So glad I came back for Storm Legion.
