Idk how pai-gow works, but i do really like that idea of capping lower difficulty scores to your highest difficulty.
In principle, anyway. But I can see a problem with it: That would further hurt people who haven;t gotten up to nightmare yet.
Say hypothetically i'm a mid-game player who's put in a bit of time, but not a lot yet, of building decent hydra champs. I can do 20M on normal, 12m on hard, and maybe 5m if i'm lucky on brutal.
That would have my score capped at 45M instead of 61m, assuming the cap is figured *after* the multiplier, if it's before then id be stuck at 15m. that or I'd have to throw away a key to not count for clash, and also miss out on mithrala shards if i haven't reached her yet
Or you could do 3 Normal runs and get 45M on each of them for 135M. Since the Cap is only based on whatever the highest one you complete with points. If you only do the same one that is considered the highest. The teams that do 500-900M on normal. Think I saw a 660M Hard posted in the reddit in a single team. Do 3 of those on Hard only get 1.92B points. Because technically Hard is the highest you did.
There is always ways to game things like that and be like I want the Accessories more than the Artifacts.
