I know there will be a tier 4 invasion, but in a while players who are interested in the game will learn and improve, and tiers will fatten.
I have no issues during EU or NA primetime playing in solo que, so prolly my tier is beefed up during those hours.
But during Oceanic prime time, this is what happens:

For those one wondering, this's not been a balls deep "stomp". In a minutes the 2 teams have reached the classic 2 hills, and stopped there playing peek and poke for 5 long minutes.
I saw people shooting with mpl a targets at 400-500 m.
People shooting at trees or rocks, without seeing that its own hardpoints were too low.
Two heroes charging all alone.
When valves get released, these matches remind me the infamous old elo MM.
I know that with fix valves it would take forever to get a match ....but after a couple of matches like that above, I quitted MWO. So, I think it's even worse.
