The problem isn't DLCs in general, but good costumes. They are lazy.
I really have a problem with swaps (Lei Fang's dress, oh my...) and recolors too in general.
I don't mind "shared theme costume" (the bunnies, the cheerleaders and the santa costumes). They are not ruining a character's identity and they are not so tempting to be honest.
But, I found Gen Fu's recolor DLC (pink/white) very offending for Gen Fu's fan. He has like..
3 or 4 amazing costumes that should have come back. His costume selection is too gritty and similar in DOA5. It's like they have abandonned him anyway. I like to play him casually, but I hate the way TN is treating him.
But overall, I am not against DLCs, that would be a lie to say otherwise. I like to see new good costumes on tuesdays, for Helena. Helena's headmaster costume was a surprise, for example. And since I only care about her, since she is my queen, I don't mind paying 1€ per month/every two weeks just for her.
I know these costumes should have been on the disk in the first place, but knowing how TN just rushed to finish DOA5 (and DOA5U), we would not have had so many costumes at the end. Costumes actually need time to be created, even the classic one (from DOA4/3/2/D). They are created from scratch, right ?
