I found that Blitz still hands you 1800 just like last season, but it seems even easier this season. On my shaman i lost 4 in a row right at the start and even after that I was still at 2k MMR. then I just went 50% winrate up to 1800. Took I think 16 games.
On my warrior I won my first 6 in a row, then lost 2, then won 2. Total games 10 for 1800 rating and I think im 2900 MMR or so.
The RNG/Lottery feels less of ‘some people get rating, some people don’t’ and more ‘some people get 1800 in 8 games, some people get it in 18 games.’
As usual the hardest barrier to overcome for blitz (and shuffle) is the boredom barrier. sitting in a queue for 10-20 minutes is actually unbearable for me
