Welp what a nice community we have.

And seeing how some called themselves carebears and are now wanting to sell that too. Thankfully I have good friends and one is a great tank.
The only legitimate reason to say that this is like crafting is, when people will go towards you and ask you if you want to tank a dungeon for them that you dont even want to run. But if you plan to take Gil for a dungeon you would run anyway..well you can try and probably will find someone but it makes you look greedy in my eyes.
Hmm time to make a deal as a DD too. If you want to have great DPS from me please pay. I mean I am only obligated to DPS at all, not how much right? /Joke
(Oh you also wont hurt SE with such actions, the only ones that you will punish with those are people without friends that had nothing to do with the jobs we get. Heck maybe some might even say that they find the community really toxic and will leave the game behind.)
Do whatever you want, just dont argue about it like its good for the community or something. And also dont forget that not every DD will have an interest in the new jobs so they also dont get new things..
