Variety is the spice of life. Some people prefer open wonder-style scattered spawns, while some prefer hilly-style clustered spawns. A lot of people like both. Map gen presently provides variety. This is a good thing. Map gen code could theoretically be tweaked to change the spawn distribution to be more or less clustered if desired, but map gen is already more than desirable enough to be included in TMM in its current state.
Some people here seem to think that 3v3 TMM would be unpopular and claim there is a lack of decent maps for it.
Some people here seem hesitant to put map gen maps into TMM.
I challenge those relevant people to try a 3v3 map gen only TMM queue alongside the other planned queues, and see how popular it is. It might be the most popular queue. I know I'd want to play it more than the other queues, and I know many others who would as well.
