Speaking about misleading kits and how personality is conveyed, how well do you think Bard performs in his role as League's resident Wandering Caretaker in-game?
While he's easily one of my favorite champions, I was never particularly successful with him--I always thought it was because I was getting chimes at the wrong time or not roaming to mid enough to drop a shrine or two for them, but as it turns out, success with Bard requires a...surprising amount of aggression, to say the least (and not really all that much wandering). Stuff like throwing an attack the enemy's way every now and then is actually fine as far as character goes--aside from limiting aggression, is also succeeds in conveying Bard as a generally peaceful dude, since in the context of that passive alone, he's only a threat when his Meeps are around to intervene.
Everything else about Bard, however, makes him seem more like a Wandering Playmaker than anything. All of the successful plays I've seen with him (particularly in the pro scene) involve huge ganks with Magical Journey, set-ups for double kills with aggressive use of his Q, and his shrines are almost exclusively used as a way to help an ally get in a position to finish a kill. Looking at every guide, it's always max Q first, build some offensive AP items, max W last, look for ganks, etc. (even Rioters on the board suggest offensive burst damage Masteries rather than anything that could be used to aid allies); so while I looked at his kit at launch and thought "ah, I should max W and E so I can roam around the map and make sure everyone is having a good time," that was ultimately the cause of me "using him wrong."
I kind of wish his kit was more about what it says on Bard's tin, although I'll still play him the way I want regardless and have fun with him win or lose. When I'm Bard, no amount of kills or assists can top the warmth and gratitude I get when I trek all the way into mid or our jungle and help one of my allies get back on their feet.
