I'm no expert on anything, I'm just a trader and a miner. My only suggestions are to remove PoS and to include Coin Control. All other alt-coins have it, and now Bitcoin Core has it. That's just the technical part of the coin.
This is supposed to be a 4 minute block time coin. There aren't supposed to be any orphans anymore at it's current hashrate. Bitcoin is a 10 minute coin. It takes 2 seconds for a transaction to reach 90% of the network, and 20 seconds for a block to propagate, so 10 minutes is a lot of time for miners and pools to know if what is a good block or not.
So TAG is a little less than half the time of Bitcoin, but it's not as big. However it still should take only at most 5 seconds for transactions to reach 90% of the network, and at most 60 seconds for blocks to propagate.
I don't know how and I don't know why, and most people could care less exactly how or why (just the coders and geeks will want to figure it out), but you take out PoS, you'll only lose those who believe in "investing" 1.5% per year.
At any point in time, now, and even in the far future, one can purchase any miner or GPU and make more than that 1.5% in a month. So, I'm just speaking from "common sense" here.
If you make the PoS a higher number, then you'll attract the hoarders; those people don't really mine, they just buy, speculate, hold, and nothing moves.
I do believe you have already sort of worked out the issue, and tagmining is the official pool. As far as miners are concerned, they get what is due them. As far as the pool and op is concerned, you got his back.
So maybe the PoS issue isn't as much of an issue anymore, as long as miners mine on the official pool. Those who mine on other pools risk getting orphans or those who operate those other pools risk paying out for orphans.
As for the rest, well, I'll HODL what I have even though it's not much.
I guess the point of my post now is, coin control.
