We know that Mechlab won't make everyone happy and we'll never get people who want to do more than we'll be designed to allow.
It's just not possible to appease the vast majority of people. Especially the fickle MWBT community. I know I was pretty pissed at the "Color-Coated Retard-Mode" Mechlab of MW4 coming from MW3 and MW2. I understand why they did it, and they were on the right track, but how they presented it made me swallow my own vomit a bit.
I also don't believe there are just thousands of people waiting in magical cocoons that will hatch upon release of Mechlab. Don't get me wrong, that would be epic, and I understand we're in beta. Though, I think we have a pretty solid mix of things in the game to at least suit every playstyle favorably.
I hope we get a bajilion more players upon release of a single coveted feature, but I'm more appreciative of the community who plays the game as we build it, sharing in the same hurdles it takes us to make it and playing along, enjoying it as it is. That's the most important part.
