Sure, but I'm not sure you realise Taric has a minimum 0.6 AP ratio, self-heal 0.84 AP ratio, and maximum 1.2 AP ratio. That's on his heal alone, and every other ability he has includes a great AP ratio (0.6 AoE, 0.8, 0.7 AoE. That's already mage-level AP ratios).

I'm sure your carry normally builds Guardian Angel or QSS. 6 offensive items melts far too easily. Even just base values makes it far more efficient to heal than to cast offensively, of course.
