How will this stop carebear alliances? I understand that there will be a bigger incentive to own fiefs thus clans want to take more instead of divying up territories, but I think it will just increase alliances since land owners want to keep their fiefs even more and will make allies in order to prevent war and continue farming xp and gold.
Also, if you were to do this, it seems to go against the xp nerf (gen bonuses) that was done months ago to reduce looms/easy xp/make things easier for new players. this makes things harder for the newer players since they will either not be in a faction or if they are will not be in a position to be a fief owner in the faction.If you were to implement this, I think that the gen bonus needs to go back to 100 or at the very least remove the cap if you keep it at 30 per.
As an aside, buffing gen bonuses will lower loom points/heirlooms in general, which have been skyrocketing lately. thay being said I am not sure if you are for or against loompoints selling for 500k+
