What’s your point?, could you provide some info on the efficiency of 4 factories in tvp?, I don’t know trasher’s league and I don’t care, I have seen many pro level tvp and I don’t remember a single one with that amount of factories that wasn’t a mech game.I think if someone want to improve the best and easiest way is following proven builds and compositions, yes, you can reach GM with unusual stuff, but will be harder and probably not efficient.
