well i wanted this kin of wards that you have to be fast with the mouse
like drag the mouse from A to B to C like this:
.................................C
.................................|
.................................|
.................................|
.................................|
.................................|
A----------------------B
like now you would have a square with the widt A to B and height to C
and depending on size it will take certain amount mana and there would be 2 sorts of wards like:
maintain-ward: using varying mana on size until you disable it or someone use a ward break spell <-(my creation to explain

time-ward: depending time on size.
thank you for reading and please tell me what you think?
