Remove Taric animation "lock" will buff solo lane Taric but shouldn't effect support-Taric
Right now it's hard to make solo-lane Taric stronger because of how much utility he is able to bring to the team, they buff his combative stats he becomes an absolute menace bot lane in terms of scraping it out AND will bring great utility.
Solo-lane Taric is also a lot harder to pull off than before because he only has one damage spell and relies HEAVILY on getting his stun off, which is now a skill shot, if he wants to start a fight. Also you HAVE to cancel his Q and W animation otherwise you are get slowed down in your combo immensely, similar to Riven and her Qs.
Removing the animation so that Taric can quickly string Q and W would be a buff that would have little effect in bot lane, mostly because he would be focused on landing his abilities and shielding/ positioning to get good heals.
However now that I mention it keeping in his animation cancelling is a "muh skill-cap" thing and when I'm able to pull off clean cancels with Q and W it's a nice moment similar to how Riven can pull off her animation cancel.
Another idea I had was giving Taric some movement speed when using abilities so that he can catch people and doesn't have to rely so heavily on his E which is highly telegraphed.
