I don't think the boss cooldown timer is as big a deal as everyone here is making it out to seem, I think we're once again looking at some hyperbolic NeoGAF reactions to something that ultimately isn't a big deal.
They're creating this cooldown period to stop people from farming their raid bosses which as a result makes their loot/rewards that much more valuable. Besides, the people who are REALLY bothered by this will just get those weapons duped anyway.
Seeing as how the DLC just came out, I'm assuming I'm going to have the minority opinion on this for a while.
Its not a NeoGAF thing I posted the official thread that shows a lot of people are bothered by this. And by all logical means its overall a bad business choice, since you piss off a portion of your fanbase for no good reason. Which is a good number of people due to the fact that this is a loot game.
With how fast information good and bad spreads on the internet. Nothing positive can come from a decision like this.
Once again this is not a MMO with a monthly fee so keeping people online and trying to make items seem more "rare / valuable" has no real meaning. Your example of duping would be going on anyways regardless of this or not. Just now people might turn to it even more so just to say "Fuck You to the system" so to speak.
They should have thought out the design a bit more on their behalf instead of using a bandaid solution like what we see here. As there will be repercussions for this if not addressed. As this is something that actually effects gameplay and how people can play. Unlike something cosmetic like exploding heads, melting bodies. This is from a pure business standpoint. Its a bad fucking decision period. Way too much trouble for what its worth.
My personal stake on the matter as how I play the game is from a neutral standpoint. As I dont really do things like farm mindlessly. But the overall decision which effects not only the IP but the fanbase is what bothers me. Not a good trend to start and they do need to address the fans with an official statement over this quick if they want to try and do a little DC on the matter before the click hungry "game journalists" decide to go and run with it.
*Bit of useless trivia. Ive been actually playing the game for a while now in a separate window.
