In general I'm a kind of people that try to see good sides in external things from me, I'm able to be easily appealed (even keeping reserves on my judgement), and of course there is a completionist side in me for getting a most possible complete experience about the things that I really like. All this is what develops in me the wish for getting the outfits of the DoA5 series. I limit it from the fact that I don't have the possibility to buy everything immediately and then I want do a sort of opposition to the current path, but in the long run I've the prospect to buy all the DLC (at least on Xbox360, on PC I will get only eventual extra characters).
By the way from a rational point I think that the casual gamers, intended how the people that are very interested to the outfits, shouldn't buy what they dislike: this is the most efficient and powerful way to make understand to the ones behind the game that you disagree with what they release (from the quality, to the prices). If everyone would make so, you can be sure that they will change immediately direction about this matter, but evidently the majority of the people can't completely consider it (as I'm guilty of), or instead could really like how the DLC were released so far (for example people interested overall to the fanservice for the females). For this reason I have a deep respect for the will of some people that even seeing outfits that they like, they never bought them just for manifesting their opposition to the prices from Koei-Tecmo.
On the other side, I believe that people that are interested overall to the competitive side of the game and partecipate actively to the tournaments, could have more interests to buy all the packs, just for promoting the game and the initatives of the developers (that like we have seen are not remained far from similar matters during all this time, more the remakes of DoA5 happened just because people showned interest to the old DLC too, doing of it a successful game from a financial pov).
Basically I'm suggesting that people should do the exactly the opposite of what are their direct interests, in favor of something more worthy for the future; the problem is that this is something easy to say but not equally easy to put in act.
