I agree with the majority of this thread that DLC has gotten ridiculous. I don't however think all of it is bad.
I've bought all of the dlc for both borderlands games (I'm aware all of the dlc isn't released for the sequel yet but I bought the pass so I will be getting it) and I feel like they were completely worth it with the exception of Moxxi's Under Dome Riot for the original game. I have also bought all of the dlc for Gears 2 and 3, and Halo Reach and 4. The dlc for these two franchises is not story based except for a couple gears packs, but I also found all of this content worthwhile. I also don't mind purely aesthetic things like costumes or music or easy mode things for single player or co-op games like buying level ups with real money for tales of vesperia. All of these can be ignored.

Now on the other hand I planned on playing Asura's Wrath until I read about the ending fiasco mentioned in the OP. I will still play it eventually only I moved it way down my list for this reason. I don't believe cutting out any piece of a game is justified in any way shape or form at any time. When I bought Assassin's Creed 2 I didn't realize until I had beaten the game that 2 entire memory segments before the final segment were not included, but sold seperately. I would not have purchased the game until a GOTY edition had come out and I don't believe I should have to wait to play a game or pay a premium. I also am one of the many burned by Capcom for Street Fighter (I waited for the Super edition but then they had the arcade edition) and other on disc bs. I enjoyed Oblivion, but havn't bought Skyrim yet for obvious reasons. I'm not fond of them releasing a buggy game and patching it later (or console in wiiu's case) because I might not have enough time to download it before I have to be somewhere or I might not have internet access at the time and be stuck with the bugged version, but this I can tolerate. It's the true ending, extended ending, missing middle scene, on disc dlc, and overpriced 20 minute levels that add nothing to story gameplay or otherwise. I'd say DLC is getting a tad out of hand would be the best way to describe it, or perhaps some developers are crossing the line with it, but if done right it can be an awesome thing that helps us get more out of what we love.

TL ; DR I agree with OP/SOME DLC is good though/Love Gare's example pic/
