I still feel that Hydro Pump is the least useful move on a mixed set w/ Gunk Shot. Aside from Heatran and a few other things, what is it hitting that Grass Knot, Ice Beam, Gunk Shot, and Dark Pulse aren't hitting? Ice Beam is still a very much needed move to hit DNite, Chomp, Lando (T), Lati@s (esp Latias cuz Dark Pulse doesn't KO bulky variants, and other things like Mence and Sceptile pre mega. I guess Bisharp can be a problem but other than that I see very little reason to run hydro once gunk shot is released.
Edit: just realized that steels become a problem, but then again HP fire > Grass Knot if Keldeo and Swampert aren't an issue. Tran really seems like the only issue.
To be fair, being walled by heatran isn't fun for any mon, and he alone makes a perfectly valid reason for running hydro pump. Hydro pump is also gren's strongest option for the rare occasion he needs to hit stuff neutrally. Lastly, hydro pump makes sashninja a very shaky check to tflame, which can be helpful.
