Whelp! I don't want be argumentative. It's your call.
I generally buy most FSDTs addon on day one. but I used to be in the camp that you mentioned before I got totally on board on FSDT. so yeah I have benefited from this group p purchase. But right now, the only addon I don't have is CYVR. Now I would have to wait till Houston.
But I was just musing it would hurt your most loyal customers though. Or rather they don't benefit. I would have thought it would benefit to reward early purchasers in some way.
