I wonder if it's a data center thing (or only some servers) having multiple tanks fighting for MT'ing in the Towers?

I've been lucky enough that on my server (in all the times going through DF, etc.), that B Alliance is always default the MT. On stuff like Cerberus, A Alliance always gets eaten, C Alliance always tanks Wolfsbanes and handles Chaining Cerberus back up.

It was that way from Crystal Tower 1 and on (B Alliance always MT'ing).
