Current "raids " are fine for average PvE players which likes to do same things over and over again. For some reason it's not boring for them. Their main reason is to do anything together and socialize meantime with others. It can be "raids" but they will be fine with any PvE content. Like dungeons, fractals or even open world stuff.
But current "raids" in Guild Wars 2 have nothing to do with real raiding experience which is focused on progression. And very organized group content.
That's why most of the real raiders quit gw2.
You can't keep raiders interested when there's just 3 bosses per year and game is missing meaningful rewards.
IMO word "Raid" should be renamed to something else. Why?
Real raiders feels cheated by ArenaNet.
Average PvE players don't like this word. They don't like raids from other mmorpg's so they avoid this content in Guild Wars 2.
It would be healthier for both groups.
