This data should be analyzed from a standpoint as to why agro decks is particularly dominating the meta. Simple reason is non-viability of control archetypes.
Control decks being the bane for agro based decks is non-existent or don't see any plays in standard ladder. This is due to the new quest/combo archetypes which cannot be countered by slower decks. Game is over before control decks can start playing their cards.
So while agro feeds on quest/combo, they are left unchecked. As balance is broken, the meta is skewed to Agro > Quest/Combo.
Hope that Bliz team can figure out a fix to the balance. Quest/Combo which can completely draw and play all their cards by turn 6,7,8 is rather problematic IMO. The value of 8,9,10 mana cards is reduced to dust as adding them to deck list will just reduce win rate. So no point printing or keeping them anymore.
