I gave up my xform on Elyos side voluntarily because of how messy the sieges are. You cannot expect people to participate in sieges forever when there is no unity, no coherence and no coordination. Sieges should be fun, but every single siege we had except 1 week or so when Hametsu was the fresh leader has been nothing but GP farming, zerg vs zerg with no actual purpose and no challenging fights to be had. It's just contribution hunting. Why would you want an xform rank when there is nothing to do with it. You can follow the leaders calls all you want but 1, 5 or even 10 xforms will not make a difference in the long run. You need the league to listen and people to be on VoIP to follow commands and provide feedback to the leaders quickly, otherwise it will never work.
Also, it did not take me long to get 5 star at all. I was almost general before I stopped (on Elyos side), and I never even did arena of harmony, arena of glory, engulfen ophidan bridge, kamar battlefield or iron wall warfront. All I did was go to siege everyday and do bastion and my solo arenas. Almost general in a bit more than 2 months of active playing. That is nothing. Climbing the ranks on this server is incredibly easy. On retail I had 128 000 glory points and I was not even close to reaching 5 star after 3 years of active playing.
