This!

Meta seems somewhat stable with most recent round of nerfs/buffs. 

I think what kind of grinds my gears a bit is the amount of RNG related mechanics that have been brought into the game.  Someone did a good write up on it recently but do not have the link.  It's just that decks like no minion mage & control priest (although not OP or even tier 1) are just somewhat frustrating to play against.  The ability to discover nearly unlimited resources that can swing the momentum of the game in an instant can be fun for some but frustrating for others.  It's also frustrating because one can put together a well thought through and tested deck and encounter one of these situations and IMHO seems to counter the motivation to deck build.  A deck like no minion mage is literally a value generate discover with a little bit of burn.  I think this has forced the game to "speed up" and create very aggressive decks that need to win out before they can be out valued. 

Still a great game and I know this has been stated here before but the over abundance of RNG/Discover has made it quite "swingy" and while fun at times can be very frustrating and might dissuade folks from more varied deck building strategies.
