i am currently playing on frostwolf as pvp player, i want to play some pve, in deathwing and ragnos most of the ppl did all the raids and frostwolf don't have much raid, what realm i should play? [i wrote that here because a lot of ppl watching loedaeron forum/
Depends on which expansion (and rates, if Wrath) you want to play.
Currently focus in on Wrath, specificly Lordaeron, which's core at some point (soon TM) will be used for Ragnaros and Deathwing aswell. It is x1 and does provide less, however higher quality content. Also, it is in pre-Outland stage for now (till first week of November, if I remember correctly, when for a month or two it will go into TBC stage and then - Wrath 3.0)
Ragnaros and Deathwing have most Wrath things, however there are more bugged things than on Lordaeron. If you want to get straight to pve without waiting and leveling too much, go there.
Cata and MoP have way less content, however, as you can see, there are still people playing it. Whenever Lordaeron is fixed, focus will be moved to one of them, Warmane Staff hasnt said which though.
But in the end it comes down to which expansion you prefer.
