This could be an advantage, could be a disadvantage.
Pros;
People would recruit more members to cover said disadvantage.
No more small to solo guilds during WoE (If people are willing to not go solo).
No solo breakers.
More classes to be utilised during WoE.
Good way to spread out the number/quantity of tokens in the server to the population. (Guild leaders would spend more tokens to recruiting members.)
Cons;
Big guilds may monopolise the whole WoE as a whole. (This is a big issue for me personally, but can be resolve by having another big guild to take over the reign.)
The economy may take a huge hit if there was a monopoly.
Fluctuation on Emperium Aurora prices again. (I may be wrong)
Valuable Emperium Auroras and Imperial Helms may be hoarded by certain party or an individual.
Again, I still don't know how to feel about this. I feel this may be good, but I also feel that this may be bad. Either way, points that I have mentioned both bad and good have been going on before already so if we manage to survive that, we may survive the change as well I guess. Sorry, I can't give you my answer but hope my two cents count. I like the idea of bonding and relying on guildmates, but I have always been relying on them anyways, even with the @storage around. That didn't really bother me so much with that around, Emperium would still be conquered by many.
Regarding the backslide issue, it's probably a bug so the GM would fix that soon enough. Big thanks for noticing it though.
