Bard ult recipe for disaster.

As you can probably tell from my name i play a lot of bard. i'm not a high rank player but from my many games i have gotten very good at using his ultimate, although i have no trouble landing it, a lot can change in a fight from the time it is cast to the time it lands, even if you are relatively close. I feel like it wouldn't hurt the game too much to have it's cast speed increased ever so slightly so there are less unfortunate moments when using it, also team mates are relatively blind to their own teams abilities (understandably) as they do not pose a threat so a lot of the time people will not even see it coming.
