Taric's early game mana is frustrating

I'm a support main. I play lots of different supports. I used to main Taric before he was reworked. He is sexier now, but I honestly don't play him nearly as much since his rework last year. But once in a while, there are still those niche games that I will play him in, and I feel like his true potential is realized at around 25 mins when he has , and possibly or . Before that, I feel extremely weak and vulnerable especially against poke lanes.

I feel like a lot of this stems from an unbalanced feeling for how much mana Q and W cost compared to the healing/shielding they provide. Other supports have similar mana costs and efficiency to taric's 3-stack Q cast, but they don't have to wait for 45 seconds for three stacks for the same efficiency, and they also typically have higher base mana and mana regen rates. I know he's tankier than those supports as a trade-off, but from an early game sustain standpoint, I would much rather have 2 more mana regen per second than 5 more armor, and his obvious preference towards where those other supports can go or doesn't help the mana situation either.

I think all that needs to be done to make him more viable is to give him 25 more base mana and 4 or 5 more mana regen per second at lvl 1.
