so if i understand correctly you would like for example a scuttle on-top of a spire to not become de-cloaked by units at the base of said spire..
so i think your asking for line of sight de-cloak.. yeah that makes sense but maybe would hugely buff some cloaked units in some situations..
as a side note considering how easy sparrow spam shuts down ultimatum counter to paladins it sadly wont help them be what they once were.. sparrow is kinda underrated imho
