Taric rework made him worse

Okay so I may not be a taric main, but I did play taric before the recent rework. Taric to me seems quite strong if an opponent were to not kite and just brawl out because of taric's passive being like a sheen which would lower his cooldowns as well making you capable of using two w within one skirmish. Taric to me always seemed just lacking as his only cc was a stun that didn't even last very long and had quite a long cooldown unless he were to be able to proc his passive a few times. Other than that, the passive armor didn't have a huge significance early game so one good thing was his heal to sustain his adc or himself. With the recent reworks however, he has potential to stun multiple targets as well as grant invulnerability on a short cooldown in theory as long as he can proc his passive. However, the problems are with 2 of his abilities. His stun doesn't last very long, starting at only 1 second and normally that would be fine, EXCEPT it's a skillshot. Most people can see the shot coming and side step before it actually lands, and even when it lands, it doesnt feel satisfying because it only lasts 1 second then that's about it. You have champions like annie, leona, warwick, malzahar who have a point and click stun or suppress that lasts quite long usually ending in forcing a player to flash away or die. Before, even though tarics stun wasn't quite long, the saving grace was that it was a target stun. Now I feel it just out right is useless as the reward you get for landing the skillshot isn't even so great. Secondly, taric's ult potentially sounds strong, but I find myself or teammates dieing before the 2.5 second delay for it to give us immunity to damage. You might be saying, well why dont you just cast it early? Why? Because when you cast it early, people usually just sit back and be like okay he wasted his ult now he doesn't have his ult. Another thing which isn't a huge problem is taric usually has no mana after a few skirmishes early lane. I understand later you can buy mana items and you gain mana per level but still he has like no mana. But again my huge problems with him is the reward from his skillshot stun sucks and his ult delay is just really bad because you either die before it works or people just back off and you wasted it. please think about it thanks
