I just did F1 and F2 in DF just to see - doing the whole thing later with raid group.
F1 was a couple of wipes and then just explaining two simple mechanics. F2 was pretty straightforward, but we wiped in the end because the other tank just wouldnt pick up any ads, blamed the healers, everyone argued etc. Typical DF crap.
And i mean it's day 1 - remember day 1 of WoD? Clusterfuck cos nobody knew the mechanics - same thing here, ecxept its just 8 people so you can at least discuss the mechanics in a calm fashion. Give it a week and everyone will know the mechs and it will just be farmable in DF.
I like that they have an EZ mode - I have a static , but there are plenty of people who don't, and simply can't for one reason or another. Plenty like this in my FC, and it's great to see that they can now jump into a raid with a couple of others from FC, or even on their own.
