Taric Adjustment?

Hey guys, just a quick shower thought here: Would it be game breaking to bump the max health scaling per stack on Taric's Q from 1.5% to 2%? I mean, think about this for a second, let's say your build looks something like this endgame:

Remnant of the Aspect Mercury Treads Zeke's Convergence Knight's Vow Redemption Locket of the iron Solari

Now, with this build right here, if my math is right, at level 18 with an elixir of iron, you should be sitting at around 3300 hp. With current Q scaling that will get you a heal of about 397.5 hp from 5 stacks (437.25 if you factor in healing bonus from Redemption) while your Redemption active heals for 481 hp, so taking Redemtion for the team heal is more worth than trying to set up your Q to heal everyone. If you were to build Righteous Glory instead of Redemption, the heal only sits at 412.5 hp I believe, therefore going Redemption is still a better option. However, if the scaling on Taric's Q were to be adjusted as I proposed, the numbers would look a bit more like this:

With the Redemption build, Taric's heal at 5 stacks would now give you 528 hp, while Redemtion would stay at 481. Taric's heal would outperform Redemption here, making redemption obsolete, especially since Taric's heal is on a much shorter Cooldown than Redemption. What about Righteous Glory you ask? Even without the buff to healing you would get from Redemption, with the new scaling on Taric's Q you'd still heal more than Redemption. With 3500 hp Taric's Q at 5 stacks would heal for a solid 500 hp, 100 hp per stack. Leaving that measly 481 heal of Redemption in the dust (albeit only by 19 hp, lol) this change would encourage Taric players to not only focus more on stacking health instead of forbidden idol items, but it would also make saving up all 5 stacks and positioning yourself to hit your whole team a lot more worth it. Please consider making this change riotgames!

Edit: Maybe calculate his Q's mana cost per stack? For example, @ level 5 his Q would cost 22 mana per stack (still 110 at 5 stacks)
