Yes, the best day for 5s is Monday (Sunday sometimes). More teams playing just for pts etc.

Also I don't think you quite got the grip on the hidden rating thingy.. I also think that the reason why so many ppl didn't play this season is b/c they don't understand it.

Hidden rating changes similar to personal rating... Let’s say you start out the season and grind your way up to 1800 (your hidden rating is 1800 also) now you join a new team at 1500. Hidden rating is made to rush you back up to 1800 where you belong. So you should win ~20 pts a game and only lose 3-4 for each loss. Now every loss will also lower your hidden rating a little.. Only if you won every match should you go ALL the way back up to 1800 easily but most likely you will even out in the 1700's somewhere.
(Oh and you will be fighting teams around your hidden ratings not teams at 1500)
Now it also factors in your partners hidden ratings when matching you up and calculating gain. So if you partner's hidden is like 1200 you will probably be even right there at 1500.
Now I'm not sure but I think it starts brand new lv 80 hidden ratings at ~1300 judging on the pt gain/loss my new DK is getting. So you should have an uphill battle on your hands for a little while when you start arena.

1 last note - I believe I read that the hidden ratings will NOT be reset with the new season. So I'm going to assume you will see teams moving up through the ranks pretty fast in the beginning.



I hope this helps some of you who don't quite understand the rating system a little.
