This gate issue has gotten well out of hand. Every Tier 3, and every going on Tier 3, has Jigsaw Valley in it, and I am downright sick of those over and over.
Now, we used to be able to at least coordinate the gates into something everyone in Tier 2/3 could enjoy. Now with millions of of minerals required, it's completely impossible, even if ten guilds were to form up an alliance just for gate moderation. And that means gates are doomed to be trashed by autosellers constantly, and there's no way to teach them now as the tutorial has gone by for most and the vast majority don't know what to do with minerals besides autosell them.
I propose letting some of the stronger players earn alloys through tokens, or whatever, so they can help with gate creation far more than someone in tier 1 could who autosells everything they grab.

This. A thousand times, this.
I would go so far as to lock players out of donating materials for a tier if they don't have clearance. T1 players can only add minerals to T1. T2 players can add to T1 or T2. T3 players can do what they like----giving them more control over the tiers they actually play.
