For the income, I wouldn’t put it tied to a guild. Anyone can currently claim a keep for their guild, even if they had no part of helping taking/defending it. Also, anyone can currently buy upgrades for it.
Instead, either have an income steadily accumulating for upgrades, or reduce the costs of upgrades the longer a point is held.
On the point of the dolyaks…. I still don’t see why the rewards weren’t reimplemented. They say it was because too many people were abusing/botting them. They even said the removal of the orbs was also largely in part of people exploiting to get them (balancing was also a large issue, but I remember reading this statement).
Instead of fixing their issues with WvW, they just keep removing things that can be exploited. How about fixing the exploits instead?
