I played Tallon Zek on Live, and, in my opinion, Cross-Teaming ruined the server. Pandemonium justified it as "zomg orange tags (Evil races) are SO MUCH more powerful than all the other teams not fair" which is true to an extent, but they just made a guild that had EVERY team in it and monopolized the server.
This forces strategy for guilds in the blueprint: Gonna have to sacrifice having some classes and racial advantages. I suppose, if allowed, guilds could just tag for every team, but come raid time this is going to cause issues, though dividing your raid groups up by teams could mitigate it alot. I voted hard-coded, I feel it adds a layer of planning that soft coded negates
