[Icecrown] Additional tallent tree

Due to the wide possibilities offered by PVE / PVP and cross-realm servers, would it be possible to add an extra talent trees? We play different spec pvs and if we add pvp, it is noticeable and difficult/annoying to change talents and glyphs depending on the needs.

Thanks.

sugested before, and denied.

The game was designed by blizzard to have 2 talent trees. if you want to change specs just reset your talents.
