I've made sure to watch every LOTS game on youtube. I have some thoughts.
1- Balance is generally good
2- In land battles, indirects and snipers are just bad. Aside from Vipers, t2 arty, and t1 arty, indirects were almost completely absent from LOTS games. I think I saw 2 trebuchet built in a game on twin river. No other games included them. I suspect the main issue is low hp of indirects - your tanks and heavy bots can survive not being supervised for 5 seconds because they have tanky hp. Indirects die too quickly.
3- Snipes are a bit too strong. Perhaps, when an ACU hits 0 hp, it falls to the ground and becomes a crippled ACU. Crippled ACU cannot move, shoot, build, regen, or be repaired, but can absorb another 10k or 20k before it goes nuclear. Just an idea.
4- T2 and T3 navy are too good. They scale much better than air and hover. Land simply cannot defend. Better shore-to-sea weapons would be more interesting than a nerf to ships, imo.
Any other thoughts about the top level games?
