It doesn't help that even with a recovery, it can go down in one turn by being double targeted. The berry it might've been carrying wouldn't even proc.
Oranguru is also susceptible to Taunt, Roar and is usually taken care of pretty quickly. Most Z moves destroy it, so redirection is very welcome and might even guarantee a free switch in for Wishi. That does take up a team slot though. Instruct helps a lot if the setup is done correctly.
You also would need some rain setter, and that can hinder team building at times. So you would basically need to run 2-3 mons to make Wishi usable, that alone takes up 4 slots. The other two will need synergize well with it.
