So here we are, 63 pages in, and people are still arguing to go do the other types of content if raiders are bored despite them saying multiple times those aren't fun.

I dislike the other class' playstyles, yet people are saying I should level them up so I can't be bored. Why should I force myself to play content I hate? So I shouldn't be angry about not having stuff I like?
The actual complaint here is a lack of engaging, fun and hard battle content. This is a valid complaint, especially for a MMO.

You can finish the content very quickly and I can understand that, but the issue with this is the lack of replayability from the fights themselves (as well, of course, of a lack of hard fights). The system is too rigid to allow deviation and it's playing against the Devs in certain instances like this one. There is so much more they could do with Raids instead of small-arena-you-can-fall-off-plus-boss (heck I suggested environment hazards for Deltascape V2 in my last post, wouldn't that have been cool?).
