here's another idea/question that might solve the hardcore raiders issue...
In the case where guilds have the option to continue where they left off after the lock-out timer expires, what if such zones also had a Max Time limit per entry?
So, any guild can enter lab one night, raid for .. let's say 4 hours max. So after 4 hours, a timer is up and you can't continue until after the lock-out timer expires?
does that solve the issue?
