@its_time_to_duel What rank are you playing at? I've been playing almost entirely TMM the past year and have had no issue with playing my own way (it's only occasionally a teammate gets annoyed) - that's been playing with/against people around the 700-1400 ratings.
As an example some games I'd be in a land slot yet not build a single tank; I've tried going for a T3 ACU and building a firebase in range of the enemy base. I've seen people make use of beetles in several games; have died to ghetto gunships, TML snipes, cloaked laser ACU, tele-SACU, etc.
While there may be a typical meta, there's still a lot of variety as people often do play their own way, and there's scope to play your own way.
Ultimately if you want to have fun by trying out unusual tactics you can. Your rank will be a bit lower than if you went of the optimal meta all the time but if your goal is to have fun rather than get the maximum possible rank there's no issue with that.
TMM also provides a large amount of map variety.
