You're inferring more than a little, as I don't recall saying characters have absolutely no choices in combat. They have more than one, just nothing approaching what they had at the point where 4e was announced. We had reached a point where we had some nice options like tactical feats and spell reserve feats and much other goodness. Sadly, the level of depth and diversity that tactical feats afforded is exactly what 4e moved away from.I wanted to know why you think players don't have any choices to make in 4e combat.
If I'm reading you right, all anyone would have to do is write a script like you've provided and they should be good for 80%+ of encounters.
Having said that, the aforementioned copy-paste tactics have been pretty much the norm so far. My group is certainly canny enough to quickly realize which of a handful of powers should be their de facto openers and closers in a given situation.
