It was certainly tougher this season but I made it to Silver I on the last day of the season. I won't play anymore in case I fall out of Silver I. Maybe it is just me but I found the season a lot tougher once the Chaos Legion cards were released and the old ones were taken away.
I got the water quest today and here is an example of a battle that I lost. If I had Alric Stormbringer, I would probably have won this, I think. Too bad, he's out of reach for me now. I'll focus on buying packs instead.
Rewards weren't great but 68 DEC is not too bad if I am being honest. Now I hope the season ending rewards will be good or at least better than they have been for a while.
