Have I botched my yoshimitsu?

There will be something of a boost/bonus, but only for pre-existing zeta relics. So you won't get anything for a novus.

Depending on what your plans are in game there's nothing wrong with some acc.

[2jays2day]

No you haven't. TBH I think the Ninja BiS actually has ACC on the weapon if you need to hit 535 ACC.

Is there a guide for what stats to put in?

If you can afford to use Flint Caviar in t13 then I think you can cap it at 16 ACC. If not and want to use Risotto I believe it's 32. You should sacrifice the crit to do this. There is a way to reach it the cap w/o putting acc on your weapon and still be a viable build but it requires Dreadwyrm pants which ironically drop from the turn you're trying to reach cap for. This is all IIRC. I'm no Ninja expert. There is a thread called Ninja Superthread that has a lot more/better info than I would ever be able to provide.
