Catchmoon + PunchThrough, bug or feature?

[xarvh]

Catchmoon often misses enemies that are very close by.
When I add Punch Through, it gets a lot worse: quite often the wave goes through and beyond enemies even at medium or max range leaving them unscratched.

Is this a bug, or is the weapon supposed to work like this?

I'm asking because I have a very nice riven with Punch Through and I'm not really keen to reroll it if this is a bug that might be fixed however far in the future.

I have problems with catchmoon and obstacles in the environment... if the blast hits anything, I don’t deal damage to the enemy... I haven’t had problem with punch through personally...
