Servers progression - What server is at what?

Hey guys, just found this great server and looking where to start and just have a few questions about everything. Have been trying to search it myself, but the answers online are limited.

1. What server is where via Progression? I'm assuming Lordaeron is the freshest - What Raids are released currently on it, and what PVP Season is it?
2. Same question for the other 2 Servers, Ragnaros and Deathwing
3. With Ragnaraos and Deathwing rates being x7 - Do people still play there often? Is raiding and PVP P2W There?

Any help would be great guys! Thanks is advanced.

1. Loraderon is freshest. Ulduar was just recently released and no guild has managed to clear it yet. ICC/ToC is still unreleased. Loraderon is currently on hateful tier in arena.
2. Ragnaros and Deathwing are at final stage, so everything from ToC to ICC is already released years ago, but perfected just until recently with new scripting. You should take note that both of them will be combined into one server (Icecrown) at may 20th.
3. PVP is not pay to win in any server, but you will meet people with with legendary weapons.. Mostly only bad/lazy people stayed on Ragnaros/Deathwing after lordareon was released. For PVP, go ragnaros, for PvE, go Deathwing. For both, come to Lordareon
