Need some help with Spirit Breaker.

As a mainly support player, who plays with my friends, I have some troubles facing Spirit Breaker. I've played for a long time, over 1500 games, through 'broken' Lycan to Centaur, and the only hero I have ever felt seriously needed to be fixed is Spiritbreaker in his current incarnation.

I keep wards everywhere, but he smokes when he charges, so now I need sentries. I use sentries but if we deny him a few ganks early, he still farms a BKB and suddenly his charge can't be stopped.

As the 5 usually, I find it tough to be able to get what I need to stop him. Even if we have an OD mid who buys his own rune wards and goes mek, and we have an offlane seer or clock (Usually clock since he can cogs as SB charges, which is the best fix we've found so far) who gets pipe, I don't know what to do.

I could go Euls, but with the duration on his stuns I usually can't get unstunned long enough to tornado myself. Ghost scepter? Makes him stronger. Linkens? Pfft, I'll get right on spending 5k for him to charge the creep behind me, or worse make it useless from his fountain when I need it otherwise. BKB? Doesn't stop his stuns!

My carries have troubles stopping him too, which is probably the biggest issue. If we put too much effort into shutting him down, then their #1 gets farmed and we have another problem on our hands.

It's not like he's useless in teamfights, either. We find Spirit Breaker going BKB Aghanims, and charging the back of the team mid teamfight, followed up with an ulti and just wreaking havoc. So 5 manning isn't really an option. Everything about countering seems like people are just stuck in the "He's a pubstomp hero" from before, and recommend warding and basic gameplay, but with no indicator, smoke past wards and immunity to BKB, stopping him is just exhausting.

I've searched Reddit, Google, and what feels like the whole internet but I cannot for the life of me understand how he's not in the pro scene. So, I would very much like to know, how do you stop Spirit Breaker?

EDIT: I should have mentioned, the teams we play against that use him have him as a support in a trilane against our trilane, usually with something like a naix or prophet on their team. My issue with Spirit Breaker is his ability to with very little to no warning, be a part of any fight at any time. Not his solo kill ability.
