+1progression for small guilds depends on alot of factors. Most small guilds never even make it to 60 so a level 70 guild that is not progressing has still achieved more than most small guilds.
Since the development team was ok with effectively eliminating decay for large guilds, i think a more fair temporary solution would be to turn off decay entirely until they come up with a longer-term solution.
With all the recent server bounces and crashes, guilds are being hit with double decay frequently. While this would be barely noticable to large guilds under the new system, it's very rough for those of us in small guilds. Although previous comments state that the decay is prorated when this occurs, it is definitely not the case with our guild. Somehow the minimum calculation is causing a full day decay on top of the normal full day of decay.
The developers said they wanted a solution sooner rather than later which is why they implemented this solution. Wouldn't turning of decay accomplish the same thing except that it would help all guilds?
The fact is that a guild of 10 or less stuck at level 60 would only gain 2 levels all year if decay was turned off entirely. Larger guilds will gain that many levels in less than a month under the new system with their massive renown earning power.
I really hope turbine does the right thing and just turns off decay until they develop their longer-term vision for guilds.
