PLD is just boring

[Bravely_Default]

Should not have a cooldown due to the vast (1/6th MP) cost associated with it already, in addition to this the largest part of the damage of sword oath is just the auto attacks and with what I am suggesting the main tank would only use sword oath very briefly (1 or 2 auto attacks and a royal authority) before "weaving" out of it. If it was found to be too strong if anything it should just have a 1 or 2 second cd and be increased if it is found to be too strong from there, but I think leaving it as having no cooldown would make careless paladins prone to run out of MP anyway.

Riot Blade exists and you'll be using it often enough to easily replenish the cost of ShO/SwO swapping.

You're also under the impression that you'd be in ShO most of the time, when in reality you'd use ShO as a toggled Rampart and stick to SwO 99% of the time, utilizing Sheltron/Bulwark/etc to make damage on you trivial. Unless damage on the tank receives a massive boost, there will still be no reason to stay in ShO and only swap to SwO for a RA + some autos.
