I agree with what your saying Blue. But surely that comes back to a player choosing a guild that suits them, I totally agree it would not be worth me paying wheels and such for a quest to not complete, again its choosing a guild that works for you as a player. We dont know yet what the new quest exactly will entail but even BB will not be able to argue a quest (codex) that can take up to 9 days to make and be given 24 hours to do is working as intended.
The current guild system is broke, BB have identified this and addressed it, I really only can see it been an issue for guilds with many inactive players, but it is the guild leadership now to address this or accept keeping inactives in the guild will cost them.
