The modern era of Twitch and Method are certain to influence the experience of things, but that's going to be a double edged sword... Both in how utterly easy things are, and in the time investment necessary. That is, until Nax. That shit was still hard. I'm very curious to see how well 40 man requirements are going to play out in a modern environment. Also the fights over world bosses are likely to be even more extreme, assuming it has the popularity I'm expecting it to have. The length of time it is going to take to get folks attuned or keyed will be a hard stop gap that is likely to take longer than the hype may last. I could be wrong. I could be wrong, it will depend a lot in how BfA develops as a lot of wow fanbois, myself included, just don't feel like playing, but would run BRD and LBRS in its original version because they were dungeon crawling perfection.
How can we predict modern hardcore asshole burn out rate, to those who just play mindlessly forever because of its addictive nature...
I predict the reimmergence of monster guilds just to have enough people to fill out a raid. How loot is handled is going to be very much the same, but also skewered. Being able to trade a piece of gear even after it has been assigned to you via master loot is going to cause issues. Calling that now.
