You can't have an optional extra in a competitive feature, because eventually people will just choose the most efficient way- which in Popwerplays case is the most boring and generic, which in no way makes it stand apart from the other features that use that same mechanic. Which then begs the question why have PP at all?
You can when the competative feature is to fill PvE buckets. When those buckets are available in any mode. You can when you have the opportunity, just as any other Commander, to make what use you see in the modes. Treat them like your fleet of ships. Take out the one you think will fit the bill.
Get all of those PvP buffs just waiting for PvP-PP and get it on. I shouldn't have to give up my choices, because you can't get a fight. Sorry. PvP is just not that iomportant.
