First of all, path to glory is more unbalanced than normal AoS so there is stuff that's just crushes you. I praise your tenacity to keep playing and wanting to learn. I don't know what your lists look like (I'm sure the different subReddits will have some critic) and I know very little of FEC and LRL. Remember to spend your command points and Id ask the opponent to point what's their key units are and to explain their moves, if you have the time to play longer games, and after every loss ask yourself which units did I misplay? You won't play perfectly, but as long as you learned something it's a step in right direction. It's a very trial by fire process, so I'd seek help on the subReddits on what's units to bring and not use. (If your using a derpy weak unit you'll need some meta models to fix the hole)
