Honestly, I find all blizzard's recent work extremely disappointing. Having their best developers working on mobile games instead of improving their successful ones. They said that co-op was their biggest success in Starcraft 2, and yet it feels like they have only 2 developers working on it. Alarak, whom is one of the most bad !@# characters I have ever seen, sadly has the worst play-style. so little effort spent on him.

Alarak is much worse than Raynor at the moment. His abilities always feel lacking compared to the other heroes, and he is worthless if not supported by his troops. Not to mention his troops are expensive and terrible at clearing waves.In my opinion, I think Alarak needs a whole remake in terms of abilities. maybe make him so that he becomes stronger the more he kills just like Dehaka. After all, he does absorb the power of those he kills.

These are all great ideas. I also think we need more objectives added in the co-op that will remove the bitterness of the repetition.

OvermindWe need a Zerg commander who can act like a support commander just like Karax and Swann.Also, I do not think Abathur as a support, he is just a late game commander that needs to farm up until he becomes unkillable.
