Okay so as we all know there are some dogis that are either event-exclusive or super, f**king expensive to craft. *glares at the WP button* Here's my question to all of you: what's the point in getting these kinds of dogis? They're no different from every other dogi and you can more or less sell all of them at AH. There's really nothing worth spending all that time and money just to get a dogi that you can just as easily lose with bad luck and a dogi ball.
My suggestion is this: make a bunch of dogis craftable like in old DBO, but instead of having to buy the materials you have to farm, tackle dungeons, and such to find them. Of course, you'll need the recipe first. Probably could put that on Cash shop or something for a cheap price that $5 can cover (Seriously if you can go out and get a burger for around that price then you shouldn't complain) or something. Some can even be event exclusive like the Santa dogi. Anyway, once you have the recipe you're good to go. No more need for Cash Shop, which comes to the second part.
Instead of being able to buy the materials required for making this dogi, you would need to hunt for them. Farm, UDs/TMQs, events, whatever. The point is that you'll need to work for them. No buying the materials from Auction House because the materials would be bound and thus can't be traded. If someone else wants your dogi, they'll have to put the same amount of work you did into getting it, and like the materials you can't trade or sell the dogi. Once you make it, it's yours and yours alone.
So now comes the question "what's the point of doing all of this for a dogi?" Well besides bragging rights, these dogis can come with passive effects that are unique to them. Each dogi can have buffs that benefit your character in some way, but to insure that this doesn't turn in Xenoverse these buffs can be helpful to all races and classes (like a dogi that boosts CON and FOC by x amount for example). The kicker of this is that these buffs don't get overridden by using Dogi balls, so you can make your dogis powerful while keeping that extra bonus. As for what dogis should be done like this, let's try and keep it to most of them. That way you can have your character look the way you want without missing out on the benefits.
