1) account power is irrelevant to matchmaking, as is your existing pool of champs

2) as is arena points during seasonal live

3) that point discrepancy for seasonal is quite normal from what I've seen.

Then I reply 

1) what's the point of account power then? Just an additional number in the UI ? Account power should definitely matter in the matchmaking mechanic along with the LA score. What's the point of putting me (18kk power) in fights against accounts with 30kk + account power? Just to give free win to accounts that are much probably spenders?

2) arena score is also a relevant parameter which could be considered by the matchmaking mechanic, last in terms of importance behind account power and LA score. Example: I have 100 LA score, you have 100 LA score, but I have 5k arena score and you have 15k arena score. It's like putting a veteran against a newbie. A player with 15k score will certainly have a much more powerful roster than a 5k score player.

3) I see nothing normal in a fight between me with 615 LA score and a dude with 822 LA score, it's a free win for the spender. Discrepancy should be 30 or less points, and account power should definitely matter

1) account power is as simple as just gearing all your vault champions - it is not a very meaningful number in anything. my account power fluctuates several million here and there as I gear/ungear and eat champs, it really doesn't matter nor indicate much except on the extreme ends (under 5m and over 50)

2) it's seasonal, nothing else matters except seasonal. 

3) a subjective stance and it definitely falls within the normal range we see in LA.

unfortunately no bugs here, just feedback
