Was just gonna make another complaining thread but then I thought these pop up enough we might as well consolidate them in one thread.
Onto my complaints:
For the third time in two days I broke a shredder and a millhouse popped out against me. 3 times they get the best possible card, when the odds of it happening once of the 10 or so times it happened isn't that high. Last game I would have almost assuredly won, but had to eat 4 damage on a minion, then use swipe to deal with a 4 mana card.
I've got undertaker into two 1 mana deathrattles to kill my 2/3 the past few days I have no idea how many times. No matter what style deck I play, if I put out a 2/3 after they put a undertaker out they have had it 100% of the time recently. I made a deck specifically to see if I get to this to happen for me once and I couldn't do it, not even once.
Ragnaros is still good enough to warrant putting on some of my decks even with it almost never hitting the desired target. But mostly it is just the most annoying thing in the game no matter which of us play it.
People top decking the perfect card, spamming sorry for 30 seconds then playing it.
Someone the other day took about 5-10 seconds to play out their cards each turn then waited the entire 90 seconds before playing again. After I conceded after getting annoyed the guy added me said: LOL REKT, then dropped me from friends. And of course there is no system in place to actually punish these people.
As an aside RNG is the worst part of this game by far and it seems Blizzard only wants to add more. Which will only serve to hurt the competitive side of the game.
