Well, having raided in other games, raids in D2 are hit and miss, some are fantastic, some suck.
Bungie has been very inconsistent; one of the major raid problems.
Do not look back with rose colored glasses and think it was all rainbows and unicorns; you will find yourself on that level and die faster then you think!
Raids were great then Bungie added revive tokens as part of a quick fix to add difficulty, primarily being requested by a minority of the player base. From then on raids had the fun sucked out of them so I quit with the last raid I ever did being Levi.
