Bard is Underwhelming

I've played him quite a bit and while I think he's fun, and I reaaaally love his Elderwood aesthetics but most of all his "voice", I think his kit is just very underwhelming.

I mean, during laning phase he's at his best, but even then he's still very mediocre. You have an unreliable stun, and a heal. That's about it until you get your ult, which does no damage, makes the enemy invulnerable, is easy to flash out of and even easier to mess up. Honestly he feels like he plays like a weaker version of Nami with weaker/delayed heals that don't damage the enemy, a worse stun that's blocked by two minions, a movespeed bonus that decays, and an AA slow that you can't give to other people. His E does literally absolutely nothing in laning phase, it's only really useful to get back to lane faster after you get finished picking up chimes or if you're roaming around and you see someone getting chased then you can help them get away with it. You are forced to spend time away from your team if you want your passive to do anything at all, putting not only yourself but also your ADC in danger while you're roaming around the map. If you wait until after laning phase to collect chimes, your passive will be useless in lane. I will admit, the one thing he does better than most other champions is burst healing, if you stack all 3 health shrines and someone steps over it, you get healed for a ridiculous amount, but even then it's still worse than a Soraka and it's easy to counter because you're forced to stand near them to be of any use and the enemy can easily focus their skillshots/cc on the health shrines when they see someone running to them, not to mention simply walking over them will destroy the shrines.

And I mean, past laning phase, what does he really have to offer besides his ult? He's squishy with low ratios, his healing shrines give very low amounts of health if you don't leave them to charge, and he has almost no damage to speak of whatsoever. His Q is a weak and unreliable stun compared to other supports and in teamfights nobody really has time to walk out of the fight to go pick up a health pack. His ult is, more often than not, better left unused in teamfights because with large amounts of people the casting and travel time of it makes results very unpredictable, and you have a fairly good chance of actually screwing your team over.

Most supports are consistently useful, while Bard seems only situationally useful throughout the entire game and it feels like you just have to be lucky because the effectiveness of his ENTIRE kit depends on a combination of your enemies and your teams positioning in ways that are far outside of your control. Maybe I'm just not playing him right. What are your thoughts?
