I personally agree with everything that has been mentioned, but I have conflict with two of starcraft 2 blog's points.

Faster shield recovery for protoss units w/in pylon range
I feel the faster shield regeneration proposal is too similar to the zerg regeneration idea. I would like to see the races distinguish themselves as much as possible. I have two ideas of my own:
1)Perhaps pylons should have a certain replenishable mana to recharge unit shields? It would be similar to the protoss shield battery or the night elf moon well. The pylons, like moonwells, could automatically recharge unit shields.
2) Maybe the rate at which protoss units recharge shields could increase based on proximity to the pylon.

Dual screen support
It seems blizzard has a tradition of leveling the playing field as much as possible. In wc3, blizzard declared a program which allowed players to change hotkeybindings a hack. Dual screens would provide players who have two screens an unfair advantage over those who do not have two screens. Instead, I think blizzard should focus its efforts toward making the user interface as efficient as possible, such that a dual screen setup would not be desired.
