I came here just to say this. I have followed the discussion on Reddit for a while now and LA is the most frequently complained about game mode. It is universally hated by the community and only seems to favor the 1% who pay to win. Yet it is mandatory for anyone who wish to reach end game. Cursed city and FW hards being nearly inaccessible otherwise.

Every day I sit through 5 agonizing wins which usually takes an hour. Every time I get pissed off because I get matched against end-game whales with the same boring lineup: 5-6 star mythics and fabian. I shouldnt be matched with these people so frequently. But I guess the players I could realistically beat dont play this mode. 

Fix the corrupt matchmaker. Add more easy-to-beat bots or just let us earn the rewards some other way.
