Bard's W (Caretaker's Shrine) absolutely sucks. Remove it and make something else
Seriously. It is so un-interactive. It barely heals even at fully charged. Takes forever to charge. Half the time in a teamfight I can't get it to land on the proper person because it has such a huge and clumsy radius.
Give bard a targeting heal or something please. this ability just doesnt work.
That or make it deal damage or slow enemies that step on it. Or make it work like a ward as well...
