EQ was my 1st mmo but I quit years back. Since then I have been on a progression raid guild in WoW. I got tired of WoW partially due to the way raids work there.
I think the problem is the player cap of 10 or 25, and the one week instance lockouts. It makes casual raiding unbearable. If you aren't in a dedicated weekly group, you have to join someone elses raid. You wind up killing 1 or 2 bosses and then you are locked out of the whole instance for the rest of the week. If you are in a dedicated group, attendance becomes mandatory whether you feel like playing or not.
What I remember about EQ as a casual raider was no size limit. You can bring 100 people if you want. If you need 6 healers you can bring 8 or 9. The more dps the merrier. This makes it a lot easier for someone who can only raid on random nights, or might not want to raid 4 nights a week but still wants to be able to run with friends.
EQ has gone through many, many expansions since I have played. What is raiding like now for casual players? Are there raid size limits or lockouts?
