and why do you think that? of course you can change, anyone can.... only thing that matters is what you're wearing while queueing the job
If you had quoted my post in context, your question might make more sense. So, to address what I am thinking you meant, the reason I
know some folks cannot change into dueling gear from work gear while constructing is because that is an issue I have in construction both within my town and in my forts.
In dueling gear, I bring 132 points to construction. Following the last jobs update that opened up all jobs to all players at level 120; apparently construction became a task that required high labor point to do, rather than to simply do
well. As such, when my construction tasks tell me I need to bring 481 labor points to the job for me to even schedule it, this means I
must first change into construction gear to get the necessary labor points, and that I
cannot change out of it once I do queue the jobs since I would no longer have the minimum requisite labor points to change gear.
Considering fair construction has a difficulty of 0, it's pretty hard for somebody to have negative LP.
Considering I haven't yet attempted construction at the fair, and the fact I posted above; I don't think it is unreasonable for me to believe that it would have applied at the fair as well.
