no that is your own assumption that stagnation or lack luster things are justifiable with saying "we do this in our spare time"
hell if this was true, wouldn't we still be on MTM2?
Not expanding? there was more hand made content by more contributors this truck pack, for example, then ever before.
was all of it perfect? debatable, but that means its open for improvement
we setup somewhat of a timeline (when most of the people helping are not in school) and try to get as much stuff done as possible (usually when school gets back in), some stuff gets let out or gets rushed sure. perfect example, shock shafts. we wanted to add those but the people doing it ran into issues and the method that they were using was inefficient so it was a group decision to leave the ones that are lined up alone and can the rest. does this mean shock shafts are never going to be added? far from it. I hate to sound like a broken record but the things I say are not excuses, they are true facts.
So then really this all boils down to a persons opinion or point of view on said matter, and I do not agree with yours at all. I talk/instant message most of the content creators on this site on a day to day basis, I have worked besides them and I have got to witness most of them evolve, expand and get better over the past few years. I have now hit a point where I no longer get messaged asking for help but am now the messenger to these very same people.
