actually i think “last minute rush” would be totally fine if there was no difference in ranking gain/loss regarding “when” are the fights done:
- if the points gained/lost are not changing depending on the enemy points gained/lost during the current week
and
- if the enemy matchmaking is not dependant upon the ranking change during the current week
(basically if there was no extra points available for ganging up / timing then ppl wouldnt go for the “rush” to begin with, and when a guild would organise a “rush” it would rather be perceived as a brag not an abuse, turning the rush into something rather positive or neutral)
then i think the last minute rush bad effect would be minimised while the benefits of time flexibility could be saved and we would keep the non-reastrained Gems of War that we know and love so much
