I've raided casually for a year. It's the only way I can raid. I quit raiding for a while because it seemed the only thing out there were 4-5 night a week raiding. But I'm able to reasonably manage the 2 night a week raiding schedule of my current guild. Even then I get tired of it sometimes.
Our guild has had trouble filling raid slots. I chalk it mostly up to summer. But I also blame burn out (guilty). AND you can get the same gear without raiding, so I've heard.
We managed to clear normal 25-man Trial of Crusader. Perhaps we'll continue to do so to the point we're geared enough to make it through Ulduar. Unfortunately I don't think our guild is capable of hardmode anything. Since we inevitably pug some slots, we always have to go through the mistakes new players make. Not to mention the ones us old players make.
Ensidia is having interviews with its new recruits and one of them mentioned how Ensidia's players don't repeat mistakes. That's the difference between clearing something months ago vs. beating your head against the same stuff.
We need the gear to smooth out the suck. ToC bosses seem to drop a lot of loot so that's good news for us. I just don't think we'll ever see Algalon. This isn't being pessimistic, even our top guild (by default, 3 other better guilds have left our server) hasn't bested him.
The casual scene is one of guilds just hoping they have enough to show up and do something for the evening. That's a low bar and lately we can't even clear it.
