Unsure what to do! Please help

So I’m at an impass here, I went Cleric>PriestC2>Paladin. But just recently realized I can’t get both Paladin C3 and Chaplain.
So my question is it more beneficial at this point to get C2 Paladin and C3 priest then go into Chaplain, or to go into C3 Paladin and something else at rank 7? Please help! I dont want to have to start from scratch again lol
