I don't think I'll ever do a D2 raid for a number of reasons. Radar's too small/in a weird area of the screen. First person PoV doesn't lend itself well to mechanically intensive environments(a big reason why I use swords so much.) Only 6 players, meaning a lot of responsibility on everyone rather than delegating individual tasks to groups as in other "true" mmo's. Being in a stressful environment is a recipe for endless anxiety, and guilt if you make a mistake. Really it's just too high-fidelity and stressful to be worth it aside from the very rare chance I play with only people I know during it. Not gonna do anything that's gonna leave me feeling bad in something as petty as a video game, so it's not worth the risk, imo.
