First; this group will require you to know every fight in firelands (heroics included). This means you should not need to ASK any questions about any boss in the raid. You do not need to have experience in each; but at least read up on it and watched a video or two. Second; you need to be geared to a proficient level. I hate to put an "iLVL" cap; because we all know different classes need different items to succeed. So, I will put a SOFT CAP of 385. If you are wearing PVP gear, or your gear is not 385 equipped, don't even bother.
This group is obviously beneficial for everyone even if you aren't a caster on a specific quest. A lot of the FL heroics are just as good, if not better than some of their DS counterparts.
If you are interested, feel free to comment here, send me a message in game on Loxness, or throw me a whisper to see if I am on. Hope to be raiding with you soon!
PS: A time is not specific; it may even be different days each week depending on group members. I know I am personally available after 6PM on most days.
PSS: If I can; I will attempt to update this post to let you know how many we have along with any members we have.
