Taric Rebalance Suggestion
Bastion is now moved onto his passive. He will now have a bar similar to Neeko to select allies to bound with.
Bravado is now on his W, passive is the same but now has an active that grant a shield. Bound allies can proc his passive too now.
Q is no longer an AoE heal now it work like how it use to, Taric heal himself and a bound ally. If selected by this ability they are also heal for an additional 40%.
Radical Suggestion down below
Since he loses his AoE heal he get a new passive that work with item. Item that can bind to allies apply bastion as well. 
now grant bastion on their target.
Taric can still heal his entire team with items. 1 with his passive 2 with item and another by directly using his q.
