Currently most of our xforms (on elyos side) are going in SWB during siege time (this is an actual trend) taking the xform ability with them, because they are afraid of PVP. This breaks the game design, because xforms are a tool to turn around sieges, and if most of them are in instances fighting mobs, rest of the players can't really do anything.
It would repair the situation if glory points would be removed from SWB and Kata, because it would incentivize the top 100 to fight in sieges in order to keep their ranks.
