Taric's early game mana costs. Riot's current opinion on Taric?
Any chance of easing his early mana costs or improving his heal value early on? Alternatively, adjustments to Righteous Glory to include armor and remove something else so he could viably build Catalyst would work.
He absolutely struggles with the bot aggression and is a superior pick elsewhere so he can skip his terrible costs. I'd love to hear some thoughts on him. 
I should add that, making Catalyst a better purchase on him lategame would be fantastic, without having to buy items meant for AP carries that end up useless on him.
early on before sighstone and sell it whenever it becomes an annoyance
and then go for high HP items, I really don't recomend it since you will be fairly squishy midgame due to the lack of HP. Alternatively you could stop on the
and go something like

and just see the extra AP as something nice to have. Honestly
is probably for him top but then you are going to be quite weak early game.
