Nah Enchanter Senna is still her highest win rate build as a Support, and trying to build Crit as a Support seems troll since those items are so expensive.

Because it's still useful for me to have it during roams, I don't have to be tied to my ADC after laning phase - but that game is a poor example anyways since jungle and mid fed and my Lucian was a one trick Tristana so they didn't play the game at all.
Sennas barely in ranged to use Exhaust, and the other options are Barrier or Ghost.
