Is this server for Hardcore Raiders, for WoW Veteran to feel at home?

I am considering of transfering. I am a hardcore raider, which likes nothing else in an MMORPG. I heard transfer to Gilgamesh, but I hear this is one of the other servers with massive amount of players.

If yes, I can be like "Shut up and take my money" to S.E. and transfer this instant.

Looking for "The" Raiding FC's on the server. Raiding is all I do. It's what makes my heart beat in FFXIV.
