Casual Raiding Evolution?

Back on Jul 14th Skunkworks, a two night per week raiding guild killed the Lich King on Heroic Mode. I mention this because it makes me wonder if more guilds, as its raiders lives change, will start cropping up that embrace a more casual raid experience. Only raiding a few nights a week, yet giving it your best when you do.

I remember blogging about how I felt I was pushing myself to enjoy a raiding environment which simply wasn't made for me. In the scheme of things it was always casual, usually only 4 nights a week when other serious guilds raided just about every night. I knew I would never be able to raid every night and was disheartened when I finally admitted 4 nights a week was too much as well.

Since then I've raided with two different, 2 night/week 25-man guilds. (I was pleasantly suprised to find out they existed.) We did alright but definitely nothing much to blog about when it came to success. We killed stuff but failed to clear Ulduar and to date, ICC. Overall you can say I'm content, but it stings that the results aren't there as we move from instance to instance. We move on not because we're done, but because we've done as much as we can do.

The reality is my current guild has a casual mindset along with a casual schedule.
Casual mindset you stroll along taking upgrades where you get them and are happy. Casual schedule you kill what you can and call it a day. Casual mindset + casual schedule = not setting a destination because you won't reach it anyway.

What I'd prefer is a middle-road mindset and casual schedule. I don't have to be the guild that killed HM-LK I mentioned above, but I would like to have at least killed LK on normal (25). At this point with a 30% buff we have no excuse for not doing so.

Hearing about guilds like Skunkworks proves what I'm asking for isn't far-fetched and in fact I'd like to believe more players will opt for this type of playstyle in the future.
