We are using this logic a lot, I think we also use it in other places.
Maybe we should just turn it to an util in the globals/utils.lua
Like...

function utils.getCurrentLevel(actor, job)
    local level = 0
    
    if actor:getMainJob() == job then
        level = actor:getMainLvl()
    elseif actor:getSubJob() == job then
        level = actor:getSubLvl()
    end

    return level
end

Probably better for a different PR, but putting it there

Oh, while I was looking at my diff I noticed that function already exists as utils.GetActiveJobLevel
