I must say that I am with Ftx on the BO issue. It really doesn't matter that much and there are really very few people that have any BOs / any decent ones. Yes, it's true that if someone played Twin rivers 5 times and watched it on stream he will have a better early game than someone who plays it for the first time. But it's not a BO that loses you the game, it's simply map knowledge and the ability of your opponent to properly scale since he intuitively knows how much mass he will have and scales accordingly.
Also, I disagree with the idea that these "BOs" are super important on 5x5 maps. There you legitimately make couple facs and spam tanks, there is no scaling involved except for maybe grabbing some reclaim. So if you just follow the most standard fac 2 pgen 4 mex 3 pgen fac BO that you should know by now you will maybe be behind 1-2 tanks or w/e. Doesn't matter.
Don't get me wrong, ladder can be stressful and it's hard but honestly, I am a bit fed up with this whole "Can't play ladder because unless I know BO's for all the maps I auto-lose". Like seriously, I sometimes come back after months of not playing and do most random shit, stall mass min 2 or float 300 power and it's still playable. I doubt people on the ladder have such insane BOs that you can't recover with whatever mediocre "BO" you do.
Just for reference when I actually hardcore sandboxed Badlands for a couple of hours and made a BO that cut every possible corner, was nearly perfect, etc. I've got maybe 5 tanks and 1 factory more min 5-6 compared to the most basic walk to hydro, make factories and pgens, spam tanks.
Now back on topic, why I don't play ladder?
- it's hard to find games, duh.
- it's pretty tiring and stressful honestly
