It will certainly affect me (I assemble T3 from its base minerals in one pass, except for the ones using G)
I'm not sure this will help much to stimulate fights. It mostly encourages stockpiling and increases the power of large coalitions. (a small nimble group of players will run out of boosts faster).
I would have preferred having unbalanced mineral respawn rates (perhaps by shard or general area, to encourage trading and inter-shard commerce) or have to some recipes use more then one mineral (ex: 4X + UH2O -> XUH2O), again perhaps with some random element over time to avoid the market balances out.
If it's to reduce the DB load, which I suspect, I'd prefer a change that increases both reaction time and minerals used at the same rate (ex: 10 X + 10 UH2O -> 10 XUH2O with a 50 tick cooldown)
