Warmane is the result of the merge of Molten-WoW and Arena-Tournament. The staff is largely the same.
I'm aware of that, although afaik the original AT project manager left long ago.
The result is still abysmal; they made a server-wipe (including hard-earned items, cosmetics, titles, mounts and donor rewards), completely stopped development, have no GM supporting or newly risen bug fixes (like CloS bug is there for a year now?) and last time I checked they barely have any tournaments or fun events (Quel'danas, Ulduar) anymore.
