So I know that the Punisher is not a great new russ option in the new codex but I am considering it with Pask for an all mech list in lue of not having and hydra models available. I recently tried it and was pleasantly surprised in a game against my friends nids when it took down, 19 gaunts in one shot, a wounded carnifex, and a unit of ravenors.

What do you guys think of this? I know that with Pask and the heavy bolters it comes out to 250pts (2k list btw) but it seems to provide the high volume of fire that I need for the list. So would you say its a worthy investment in this situation or do you have a better option that I'm maybe overlooking?
