How is Taric's ult considered balanced?

Super long delay on it. Don't get me wrong though, I think it's a super boring and dull ult. Main disappointment I had with the rework.

Well for starters it's got such extreme visual queues around the ability that if you miss it you deserve to lose. It has a 2.5 second delay before granting the invulnerability, which is plenty of time to run away, and it only lasts for 2.5 seconds, which is very easy to work around.

It's no more complicated to deal with than Kayle's ultimate.

Because it takes a full 2.5 seconds for it to prep up, it only gives the invulnerability to people within the circle AoE between Taric or his W-bonded, and has blatantly obvious visual effects to give away it's setting up?
