Firstly dlc in general.
2ndly still think any dlc above game price is weird.
FML for not giving AF that the game could be good.
DLC has to be developed, does it not? Do you think people shouldn't get paid for content?
On the price, I would say it depends, this DLC was what, $20 versus a $15 game? Not that bad, IMHO. The price of the DLC should be equal to the value. For me, cosmetic DLC has zero value. Adding new areas, dungeons, maps, weapons etc could be valuable enough to pay for. Kind of like WOW expansions.
How do you value "fun"? Surely being entertained, engaging with friends, competing against others is fun to some extent, isn't it? This game cost about the same as 2 pints of craft beer. I'd say it's more fun than 2 beers.
