I deem action number thing important because it would help us learn how long battles could last in which scenario and hence be able to predict at what point exactly battle would end in case it wasn't complete annihilation.
Loss of info on grid thing ofc isn't okay, but if somebody comes with a genius twist for grid that would somehow show us everything, then it's worth considering, otherwise not.
As for Creature ID, indeed it does help tie specific creature with whats going on, but what I proposed that instead of it you put slot number, creature level and creature type name y
