The new warlock card stealer of Souls is the only thing breaking wild, otherwise it's fine. Definitely some underpowered classes though. Mage/warlock/pally are the kings
The only thing? Hardly. Lets review:
Thoughtless aggro decks have unlimited and cheap buffs. Did you clear the board? Doesnt matter. Reload full board next turn plus buffs. Did you clear it again? Nice job - sorry...reload again. Full board and buffs again. Its fucking endless. Aggro has NO counter. Taunts dont work, clears dont work, nothing does. Oh and paladin gets to have divine shield on their guys too the entire game. Real nice job, Blizz.
Pirate Warrior is another perfect deck for the eh-ham "intellectuals" to abuse. So many heavily under-costed cards that are extremely hard to remove that just wreck everything. Its so stupid.
Warlock and that Dark Glare thing - another beauty. Draw 10 cards per turn, redo hero power, take damage, huge minions come out, draw more, I dont even know WTF is happening during their turn. Its a good time to go mow the lawn.
Secret Mage - yeah, its beatable but they MUST draw sort of bad and you MUST draw great. Otherwise, its obscene how much value and tempo they gain with free 5/5 minions and the secret synergy.
Now, here is the deal: Those decks would be OK IF the game gave us a legit, reasonable way to counter them. But they dont. Any counters that do exist are horrible cards, too expensive, dont really help or they totally cripple your other match-ups. Thats what ruins Wild mode. Its fine to have some crazy decks but give us a real way to screw them up. These are things to fix wild:
Make minion buffs cost more mana. Like way more.
No more zero cost cards. None. 1 is a the minimum except for Shadow step.
Get rid of paladins "divine shield for the whole game" BS. Thats total crap. Make it for one turn only if not just delete it all.
Give us a real secret counter that truly hurts. Eater of Secrets blows. Flare gets stopped by Counterspell & Yogg. Just no way to counter them and playing around them is a bad strategy and rarely works.
Wild needs some work, for sure. Im sick of games being decided after the first few turns or the matchup screen. There is NO skill involved in any of this either. Its 100% matchup and then pure early draw based. That decides every game from D5 on down.
