In another thread, I compared power names to "macros" in a computer game. If many or all of a PCs powers are named "macros" then players (either through laziness or through the desire to speed up combat) will resort to calling out the name of the macro to represent a more interesting and complex move, reducing the narrative feel of the game. To save time (or as a lazy player) I might tell the DM, "I attack with Tide of Iron," rather than saying "I push forward with my shield to bash him and attempt to push him back."
