I transferred to Bleeding Hollow a month or so ago. It sucks. I would warn others to stay away as I have regretted the move since day 1.
Bleeding Hollow is full of bots. I have never seen so many bots. They are everywhere.
The Horde population is out of control. Good luck questing if you are Alliance. You may as well forget dailies unless you enjoy spending 4 hours to complete a single quest.
The realm economy is total garbage. You can't make any gold on the AH as the undercutting is rampant and mats sell dirt cheap (probably due to all the bots).
I have only seen a single MoP rare spawn in the past month. I farmed them frequently on my old realm.
Do yourselves a favour, if you are thinking of coming to Bleeding Hollow...don't.
having played on atleast 10 different servers at max level i can sadly say, despite what others want to believe, all of this is 100% accurate. the undercutting is the worst of any server i've yet to see, usually profit is so marginal that it is not worth the time for more professions to do anything really. the ganking IS out of control and i did have to gather a pvp set just to do dailies ( i wanted to forget about pvp on my druid when i came to BH, that obviously has not happened). But such as it is, i try not to complain...
edit: came here in january of 2012 and have regretted it ever since, sadly i've yet to meet more than 2 or 3 people, it does seem very unfriendly and elitist frommy pespective every other server i've played on i always knew tons of people, made lots of gold, never had a problem with dailies, etc etc etc. but thats the reason i joined flag, now that i dont pve at all, i guess its nice to have some buddies to back me up on this server.
to clarify it is something you should really consider if wanting to transfer, its not for everyone by any means
