If I were to buff Bard
So after making Bard my support of choice since his release here's my thoughts
Chimes give 1(maybe more) gold -You aren't in lane soaking up that scavenger gold so it's a nice little something that makes chime hunting less of a burden.
E gives (super low amount) passive auto attack range with each rank -I love Bards passive but hitting targets late game is suicidal unless you build tanky. This allows Bard's passive to be continue to be useful at all stages of the game without overpowering his laning or restricting his builds. As an added benefit it gives a reason to put points in Magical Journey beyond the first and gives incentive to put any ranks into it in ARAM.
Allies near entrance to Magical Journey gain vision near exit of Magical Journey -Yes there is some additional utility here by getting vision but most importantly it stops Bard from trolling his teammates either intentionally or unintentionally.
Tempered Fate -This is a good example of an ability that defines a good player versus a bad and I do love the ability and the many different ways it can be used. However I have a problem with any ability that has no distinguishing difference between an allies version and an enemies version. I'm not referring to visual effects here. I cannot think of any other ability that's effect is identical no matter if an allied champ uses it or an enemies. I don't know how to change the ability to correct this but keep it's identity. I would like see meeps incorporated into it some how because they are awesome and deserve love, attention, candy, and snuggles.
