True, with no real motive to level a guild much more after a few levels...this change isn't really necessary for non-trans WoE.
For trans WoE, it still would help greatly...especially now with two very powerful guilds dominating the WoE scene. Being well geared is important now more than ever for any new guild that is thinking about WoEing, so if they could get those "necessary" levels for e-call fairly quickly, they will be able to focus on gearing so they stand some sort of a chance against the current WoE guilds.
Although from the looks of it, increasing the max members allowed in a guild might prove more helpful than anything
