Thoughts on Bard

I will go over his kit with his passive last:

Q - Okish in jungles, extremely hard to hit and outclassed by a lot of other stuns such as Thresh, Blitzcrank, Leona, Annie, even Veigar, hardly a form of poke with its really really short range W - Holy mother fucking mana sink batman! 100 mana at rank one, I understand it is supposed to last as long as someone steps on it, but it is still so expensive that he runs out of mana placing shrines and then cant use his Q, he could technically get chimes, but then he leaves his adc for a while and mana regen is shitty still with chimes E - Great for setting up ganks if you are on the red team, otherwise mainly used to collect chimes faster, good for initiating a baron/dragon, okish for roaming, but other than that there is hardly any reason to level it up after one point until other skills are leveled, I don't like that champions can still be cc'd or hit while on magical journeys, but I guess it is so people are not untargetable all the time R - One of the biggest account gambling ability in the game, if you miss it and hit your teammates in an important fight, you get 4 reports on you, if you hit the enemies at the wrong time or other things, you also get reported, if you miss it at all, you get reported, great gamechanging ult, but one of the most unpredictable ones as anything can happen as someone derps into it

Passive - coming up next. His passive is a super late game gimmick, it starts becoming noticeable at maybe 40-60 minutes in the game, and you can't guarantee people having that long of a game. The xp gain from chimes is laughable, if you spend a while trying to get chimes, you will be many levels behind the entire other 9 players. The mana regeneration is also shitty, it doesn't help that his mana costs for his w are so high already and he barely gets any mana back. Movement speed boosts are short enough to not make him roam fast enough to collect enough chimes and it is a bitch if you get hit by anything in the process as it stops his speed. His meeps take a very very long time to become more useful to make it worth auto attack trading in bot lane, and by the time you get to that point, lanning phase is over in bot lane. The whole point of making him having to auto attack to use his passive is double edged as he can't always auto attack and the splash is very awkward as well. The meeps though late game are the only form of damage he will have, assuming he has a late game.

Basically you can't really build Bard as a mage because he has hardly any scalings worth it (cosmic binding to unreliable and not enough source of damage, meeps not going to help out all the time, heath packs not going to be used that much later on) so you have end up building him as a tank, essentially he is a way a support form of Nasus, he ignores everyone all game and becomes a tank but still does damage with his infinite scaling.

Several things that would be nice:

1. Cosmic binding should have it's range increased and probably the amount of targets it can seek out increased and maybe a higher base damage.
2. Shrines should have a larger cap than three shrines, three shrines wont do hardly anything late game when no one is near them because you dont have much of a space to place them, maybe we can have it that picking up a second shrine in a certain amount of time is reduced healing but we can have the shrine's mana costs reduced and maybe hold a few charges.
3. I have no clue what to do about his magical journey, maybe make it deal damage to enemies and heal allies that go through it and can only be proc'd once for the heal/damage?
4. Give Tempered Fate either a range boost or a radius increase with each rank up or something, the only thing it gives per rank up is a cd reduction and increase the missile speed.
5. Make more chimes spawn faster and make them a bit closer to Bard or "smarter" so they don't spawn in the enemy spawn fountain or right next to an enemy turret.
6. Give the last set of chimes about to expire a red icon marker 1 minute before they go away so Bard knows which ones are about to be lost and prioritize them.
7. Give him an attack speed boost somewhere in chime collecting so he can get off 4 charges eventually.
8. Chimes' xp/mana gain should increase a substantial amount and scale better as well as make the movement speed buff last longer and possibly not stopped by a stiff breeze in the wind from a minion's auto attack
9. Don't know if this would make him "overly broken" but chimes could give him a permanent AP boost (3 ap per chime for example which is about 300 AP at the end of a 60 minute 100 chime game) so he actually has some scaling with his meeps, cosmic bindings, and shrines.
