Ideas for minor tweaks to Taric's new abilities

I've been playing League for a little over 4 years now, and Taric has always been one of my champions. I like how he played, and I love his rework. I think his Q - Starlight's Touch and his W - Bastion could use some minor tweaks so that he can stand up to rest of the crowd with his fabulousness.

1. I think Q - Starlight's Touch should either have the base heal per charge rescaled to 15/30/45/60/75 from 20/30/40/50/60 or have the scaling per charge changed to (2% bonus health) from (1.5% bonus health), or even have both if need be. This should solidify his heal as being good, but not overwhelmingly strong.

2. W - Bastion is the bread and butter of his kit. It's what makes all of his abilities flow like his beautiful locks of hair. Shouldn't Taric, then, be able to affect the scaling of it himself? I feel that the shield should be (5/6/7/8/9% of Taric's max health) or (6/7/8/9/10% of Taric's max health) instead of (8/9/10/11/12% of target's max health). This type of scaling rewards Taric for building tanky, like he should, just as his Q - Starlight's Touch rewards him for doing so. This should make Bastion feel more rewarding and have it compete as one of the abilities that need to be maxed first.

I don't think these tweaks would make reworked Taric too strong, but allow him to be more of a solid pick and compete with some of the other top picks. Let me know what you guys think in the poll and the comments.
