I recently started playing again and... nothing has changed unfortunately. It is still hard to get DL for many smaller clans and it is still a dynasty for higher clans. While I have no problems with the higher clans in Morrigan, its still a join or nothing situation.
In regards to the title topic, what would shorter windows do? Higher clans still need the gear anyways and won't that get them to stay dominant for longer periods? As I see it, there is no attainable solution. Any endgame clan won't leave Dl+ alone we add 4-5 stronger armor sets soon, then it'll reduce demand just like frozen.
I am not too familiar with guild wars 2, but I've heard that everyone gets loot regardless. Interclan teamwork is rewarded upon and acknowledged. Instead of a lock system, why not do a damage system?
Clan A gets 50% DMG on Boss
Clan B gets 25% DMG on Boss
Clan C gets 10% etc.. etc..
Clan A gets 4 drops
Clan B gets 3 drops
Clan C gets 2 drops
All clans get the same type of loots but Clan A gets more drops. No clan gets staggered, only clan that fails are the ones that don't show up. The only problem with this system that comes to mind is that one clan gets 90% DMG, but that can be fixed by maxing DMG at 50%. Clan A gets 4 drops regardless. If Clan B and C also camped, they also get rewarded if they at least show up on time and do as much DMG as they can.
