You are well aware, of course, that I never ever wrote against changing this for bigger guilds, mind you!
I do not think that returning to the old system is any viable option. Nor does the overwhelmingly vast majority of this community, as far as I know.
I never expected my guild to reach lv. 100 anyway, not under the old system, nor under the new. I would be happy with reaching and maintaining lv. 85 and the best guild ship. Now, with the bigger renown decay for small guilds, the best I can hope for at current decay rates is lv. 77 - lv 79. So of course I advocate for change again. May I remind you that under the old system I would have eventually reached lv. 85 with my guild.
I think the new system benefits big guilds and big guilds only. If Turbine wants to do away with small guilds, they could at least tell us to get lost and stop posting in this thread. But as long as small guilding is an option, of course I will campaign for better conditions for small guilders.
They changed the system once. They can do again.
