Laning vs Team fighting when playing Taric
I'm not sure if this is just a low elo mistake, but I have noticed that some people keep Taric linked to the ADC when they finally reach the team fight phase.
I can understand keeping him linked to the ADC while laning because you really don't have any other choice.
Your job at that point is to basically keep them alive, so yeah, that makes sense.
However, once you move into the team fight, I honestly think you are better off swapping your partner over to the tank.
They will have significantly more health, and they will most likely already have some resistances of their own.
The bonus armor and shield based on the target's max HP from your Bastion and the small amounts of health you provide will go much further toward their effective health.
Also, if everyone is positioned correctly, your stun should be much more effective coming from them than the ADC.
From the enemy team's perspective, this makes the nuisance tank much harder to ignore, drawing attention away from the damage dealers.
Imagine trying to put down a monster who is occasionally getting heals, bonus armor and shields, throwing out AOE stuns, and suddenly becomes invulnerable.
