As taliyah, Level 11 isn't too suitable because she can only roam around and make plays. It will reduce the cooldown but do nothing else damage-wise.

She starts coming online during the mid-game. Her burst damage is very significant, and she can quickly get picks with her abilities.

Her first ability will be maxed out at level 9. She can deal much damage now, especially when fighting near the objective pits or choke points.
