I was thinking about Cryodiil.. and wondered if i am the only one who is going to try to level to 50 in there??

Me too and i hope you will have the same lvling speed as the pve player.

Depends i guess on how exp is awarded in PvP. If its just from kills and capturing objectives, questing might be a little faster. But if there are PvP quests and such might be equal or so.

Personally I'll be doing a mix of both, will quest for about 10-15 lvls then try some PvP for awhile then go back to questing.

I'll probably do a mix of PvE and PvP...

Zenimax has said in a few interviews that there will be some PvE action in Cyrodiil as well. However seeing as you can not go there until level 10 and you get auto leveled to level cap when you do go to Cyrodiil, I don't know if leveling there is going to be possible...

Pretty sure he was meaning lvling by doing PvP in Cyrodiil.
