Riot, Bard's health pack cap is a problem.
Here's why.
I'm a Bronze 3 Bard main, so you have no obligation to listen to me, but I usually like to leave a health pack at top, mid, and jungle early game to help with people's sustain. The problem with this is that I'm now restricted to how many health packs I can put in my own lane until the laner's pick theirs up, and I don't want to delete them by placing more health packs down because you never know when they could use them from an ignite.
Here's what I suggest:
Bard can have up to 6 health packs placed down at once, but only 3 of them may be more than 3500 range away from him. If he is away from more than 3 for more than 1 minute, they will automatically disappear.
This helps with his lane utility while also allowing him to be useful in other lanes early game.
