As a lordaeron very pvp focused player(Tazu) (I only do pvp and VoAs, no other raids), this is a change that I gladly welcome. So the argument that pvp players have no incentive to play on Lordaeron is very biased I believe.
*Premades are finally alive again, we did full 15 man premades yesterday and we won every single bg (dominated 95% of them).
*Que times are now significantly lower, as a player who doesn't enjoy playing solo in bgs, be it Lord or Icecrown, I had to wait 15-20 mins for my 5 man premade to enter bgs, whereas now we wait 6-7 mins on average for a 15-man premade.
*Only aspect currently not enjoyable, is the hate between Lord and ICC horde, with Lord mocking them for paying for their gear, and ICC mocking us for being dead (which is obv. not true). This is something that I can live with and I knew was going to happen.
So next time before starting to flame about how bad this change is for pvpers, ask a real pvper first. If you really claim you are a pvp player and you still don't have people to do bgs with (even if it's 1 person), then something is wrong with you.
Finally, I want to say that I played on Icecrown and for me personally Lordaeron is a far superior server - exactly because it means working for everything you need twice as hard. If you think about it, the server is now even more challenging and it is something I am looking forward to.
