I recently granted a Paladin to level 90 and I'm playing Holy currently. I've looked for guides on what statistics to gear for and both are saying crit or mastery. I've gone with the crit build as it made sense to me (chance to heal for double, Infusion of Light passive) but all of the players I see on the ladders seem to be gearing for mastery.

Is there any difference, or is it mainly preferential? What do you think is the best for a Holy Paladin?

I'm also curious on trinket priority. I play a Human, so I don't need the Gladiator's trinket, but I also see a lot of top players using the Battlemaster's Trinket, is there any reason why? I've only ever used it on my Restoration Shaman because they're easily focused, so I'm not too sure about Holy Paladin.
