Taric improvement ideas

Hello everyone, I'm a support main who's played the majority of support champions in the game at one point or another since season 6. Anyway, I'd like to give one of my favorite support champions, some love. According to Op.gg, he has relatively low usage and utility, and while I enjoy him, he suffers from a couple problems. Basically, I feel that you can shut him down with cc more easily than you used to in season 7. This is due to the increase in cooldowns on his abilities, and a greater amount of damage in the meta. Also, I find his passive of limited use because even when they're empowered, his auto attacks still only do a tiny fraction of the damage an adc does, and because I don't want to accidentally take away a kill from them. Also, in my opinion this ability doesn't have great synergy with his spells and doesn't give him any options to deal with ranged cc like . These champions render him very, very difficult to use. I know that tank vs range usually favors ranged, but these three take it to a whole new level vs taric. Usually, I end up waiting till late game teamfights where I'm not dead weight. My idea for his revamped ability is to take advantage of his unique binding: Every time he uses a spell give him and the champion he's bound to a certain small percentage of tenacity(spell effect duration). Not a lot (maybe 5-10 percent or so for 1-2 seconds), just enough to help him and his adc avoid being dead weight. This could stack up to maybe 20-30 percent if he used all his abilities. The reason this would be good is that he would no longer be quite so easily counter-picked, would be more useful in teamfights, and would make him more interactive. I also would like some minor buffs on dazzle (cd down or range up very slightly, because he now has to play very carefully around blitz and thresh), but the ability change would be an awesome start.
