Wall Slam?

[LastFootnote]

I don't think I understand this feat at all. First, why is it called Wall Slam when no slamming seems to be occurring? But also, like, can you hold yourself up between two walls? Or is the intent that you're clambering up onto one of the two required props, so this doesn't work in e.g. a narrow hallway? And then why are you Tripping an enemy at the end? Wouldn't that be the hardest thing to do once you have a height advantage? Plus the feat doesn't require you to actually end up at a higher elevation than your target? I'm just so confused.

I agree, I have a hard time envisioning what this is doing with the two walls. The best I could get to is that you're kicking off walls to get height and then flinging yourself at your foe to topple them... but it doesn't seem right.

Mechanically, this feat also baffles me. It's restrictive on the requirements to set it up, and then it costs two actions to get... two actions with the second action having a minor boost. Really underwhelming.
