Tear on Kassadin?

well, not to sure about kassadin but according to http://www.mobafire.com/league-of-legends/kassadin-guide some have seraph embrace which builds from a tear. you can do it but then you'll proably lose out early dmg

If your in a matchup can win easily early on, I wouldn't. Since it would gimp your damage and chances of winning lane. If its a bad matchup and you just want to farm until late game, I see no problems with it.

I used to always stack tears on Kass before his nerf back when i mained him in season 3. I don't think it's an optimal choice now anymore
