Some personal observations:
1) Was quest rogue troublesome? yes when a player had a dream hand it was very hard to stop. The deck itself is fairly complex and needs to be played with max efficiency. You need to know when to trade your chargers in or when to hold them back and wait for the quest reward, especially versus aggro. The deck may not have been fun to play against, but it certainly was fun to play. The win rate was around 50% - I don't understand why it was nerfed like this, unless they are introducing a way of multiplying cards in the next expansion - they've just killed off quest rogue.
2) Now let's have a look at Jade Druid... little thinking with little skill required, zero strategy, curvestone with endless value that spins out of control, not only can it go toe to toe with aggro it also outvalues all control decks most of the time. And as a result of quest rogue nerf - expect to see a wave of jade druids until the release of next expansion and probably beyond...
3) Primordial Glyph is a hugely frustrating card in arena, but it is just fine in constructed. It requires a high level of skill to know which spell to pick (especially as a lot of choices see zero constructed play) against different deck types. Picking the right card from primordial glyph is often the difference between winning and losing for control mage.
4) Expecting to see an absolutely broken discardlock deck either after the August or Nov/Dec expansion.
5) Moving classic cards to hall of fame and claiming the classic legendaries are the "face" and "identity" of Hearthstone doesn't quite add up.
