Ayup!There can be a degree of tension between focusing on the success of the PC, playing the character but not their mechanical optimum, and playing to be entertaining.

Oh, just watch me.Normally you can't aim at all of these at once - perhaps you can while RPing a shopping trip, but probably not when (eg) confronting a Type VI demon.

Let's say I'm playing a back-stabby Thief. Success = 1, dis-optimization = 2, entertaining = 3, and here's how I could try to hit each:
I can start by taunting the face off that demon in-character instead of doing something more belligerent (2 and 3) while moving back into the shadows. Next I could sneak around behind the demon and try a backstrike on it (1) which even if unsuccessful will distract it a moment for the front-liners. From there I could stay in melee with it even though I'm not front-line material (1 and 2) or I could step back and search for any loot it might be guarding (1 and 2, and maybe 3 depending what I find).
Admittedly it's not easy to be entertaining during combat; that more often comes out in role-play moments.
It's a bit more I do my thing, they do theirs, and the whole is the sum of the parts whatever those parts may be.I don't know how Lanefan resolves those tensions, or expects other players to do so. Presumably players who are prepared to sacrifice their optimum in order to be entertaining would be capable of the sort of respect for other participants and mutual reciprocity that @hawkeyefan and @Campbell posted about upthread, but Lanefan disagreed with those posts. So as I said, I'm not sure.
