The lag was bad, but it's gotten much better. The A.I. needs tweaking, but I've had moments where I honestly thought I was playing against a human, only to find out that it was actually a bot. Other things need tweaking as well, including body types, weapons and abilities.
The only glaring issues I'm having with this game at the moment is the way they've incorporated the multiplayer, the fracturing of the community and the lack of actual game modes.
But I don't think the developers want this game to go down into flames and they'll try their best to make things right. You can either be patient and wait for the improvements or you can sell the game as you intend to do and basically throw away your money.
They need to be more active in telling us what's going on and they also need to use the in game notifications system. Only a small majority of the community is going to come here and the majority are being left in the dark.
Anyways, that's just my two cents.
