People may be missing the point. As an all the time spell, it sucks - yes. As a situational spell...it rocks. Prone from grease, ice, etc. = 100%. MM is the only other spell I know that has 100%. Also it ignores line of sight.
Yeah, I think that a 1d8 infini-cast cantrip which you can give a 100% hit rate
and with no line of sight requirement is pretty op. Wizard to spam grease and ray of frost and run in circles with mage armor, 16 dex and armor of faith from shadowheart, who hangs out safe from harm nuking all the greasy enemies for 1d8 per turn - or 2d8 with potion of speed.
