New player, always start on frostmourne??

Is this the best way to start? i just downloaded client, should i start here then wait to migrate? or bounce straight to icecrown? is it really just a way to make it easier to level? thanks for any help

it depends what you are looking for...

Level up is easy on both realm (thanks to x7 exp)
The only problem is that most of time there is queue on Icecrown realm (premium account can skip it)

yeah but one is progressive and says challanging pve. is it even worth playing new player server? or just skip right to icecrown?

In a nutshell:

Frostmourne offers you more learning opportunities since less carrying and harder content, you do probably have a steeper learning curve but imo that's better in the long run. Icecrown has a bit of queues going around at peak times, you do get carried by a lot of high gs people in everything but that also gives you less incentive to improve which results in more... well, 'noobs' going around. Also, Icecrown has much higher gs req for ToC and ICC which makes the area between 5k and 5.5k gs a hell to get past without the help of a guild. On the other hand, going into Frostmourne you'd be kinda late for Naxxramas and Ulduar progression, and stuck with ToC as your high-end raid for the next few months. With Icecrown you get ICC and RS from the get-go.
