Why is it still called a "raid" when it drops you straight into a circular/square room with the boss in it? Isn't that a "trial"?
I think 8 man raids need to take a page out of the 24 man raids' book and make them actual raids again. When you queue in and it just drops you into a fight with the boss, it's boring. You could structure it to have multiple bosses, each with it's own loot pool. 1-3 mini-bosses that drop minor things like upgrade tokens or rare crafting materials, just to name a couple things off the top of my head. Alternate paths that change the way the raid works, maybe even optional puzzles or battles that reward you with additional cool stuff for clearing them. I think the last time we had a raid that legitimately felt like a raid was, well, T1 & T2. The first had a mini-boss as a gatekeeper with actual mechanics you had to pay attention to, some trash between it and the boss, and honestly what I considered an interesting fighting area with multiple platforms at staggered heights. The second had alternate paths that changed the way the boss at the end behaved depending on the route you took, which is something I'd like to see more of.
Alexander tried to follow this shtick to a degree with Faust & some trash mobs (plus an entire trash pull for a "boss", but we don't talk about that), but Omega completely dropped the ball on this. Every fight was just a boss fight by itself and nothing more.
I'm sure some are going to spout something like 'that's too much wasted time, just gimme muh loot', but personally, I find the way raids are currently structured to be extremely shallow & lacking, no matter how colorful the actual fight is. I just wish they'd do something to spice them up a bit, or at least not just give us a trial fight and call it a raid.
Edit: For the record, spicing up raids =/= more bland trash. It feels like some came to the conclusion I wanted more useless trash, and I don't. I would, however, like pre-boss raid combat to be rewarded, be it with drops or mechanics that carry beyond those battles themselves.
