What we arrive with is a mechanic that is strategically void. Proton Charge provides no choice; if you do not use it, it serves no purpose, and is wasted. A Protoss Zealot standing in your base can still be used to defend if you are attacked. A High Templar not casting Psionic Storm is saving that energy for when it is needed and useful because Psionic Storm has variable uses and times to use it. Neither the Zealot or Psionic Storm is reaching their full potential by being idle, but they still retain potential itself. An Obelisk not casting Proton Charge is wasting the ability, because it only serves one purpose, at only one time. APM sinks are mindless. There is no choice to them other than either you do the required task every X seconds, or you don’t. If you don’t, your chances of losing increase the longer you do not use them. They promote tedious repetition. You cannot use them to provide benefit because everyone is using them, but if you don’t use them you will suffer. The reason StarCraft survives even with spell-based mass effect is because spells have a chance to fail and have counters. Proton charge has neither drawback in any great quantity. What we end up with is a mechanic that offers nothing substantial to the game, but consumes time that could be better used on actual strategic action, and promoting real skill.
