So, we have a LOT of topics about everything, many are similar or even identical.
What I have in mind is a "suggestion for suggestion", to give a priority to changes.
How do that? With vote (maybe a pool) or simply looking how many topics are talking about certain arguments.
For example looking at the number of threads those are some suggestions with high feedback:
Problem: buying something from NPCs vendors is painful due to high number of trash/useless items.
Solution: proposed solutions include auto-stackable items (NPC repair aumatically weapons and armors sold) or NPC don't accept some useless stuff.
Problem: some skills need fix or improvement, like junk gathering or repair.
Solution: lower again junk cooldown to 2 mins and make Repair skill cooldown stackable to 20 mins.
...and so on.
When we reach about ten suggestion we can vote them with pool, choose the ones with higher votes and move them to "high priority suggestion".

Edit: also I think that suggestions for "modify" something pre-existent get automatically higher priority than "create" or "add" something from zero.
