Not really, just putting in opinion.
But in terms of Cash Shop, it should really be a 'bonus' and shouldn't give such a huge difference inbetween non-cs users and cs users. So things like the pets and storage space packs are great. Same goes for the eyes/miles and exp increase, no loss when you die.
Also, if they had different sets for each class I would think it gets quite tedious. Not to be 'mean' or anything of that sort but what makes you think that they'd be able to do that when they can't even get patches/updates implemented correctly... :/
