If we could do it in one night, id be happy, but our raid schedule a week is basically
EV NIM 30-45 mins
KP NIM45-60 mins
EC SM60-90 mins
EC HM2-4 hours
SM Random for BH Comms
Then it would be terror from beyond. Thats six days a week, and i dont know a single guildie that would soon want to make it seven,let alone be able to make all of these anyway.
I put in red the average time it usually takes me to compete these raids in a competent pug, I would assume you and your guildies would be able to raid at least 2 to 4 hours a night, and could easily reduce your 5 day raid week into 2 or even 3. There is also the question of kp/ev NiM being worth running anymore, especially with TFB SM dropping campaign level loot, but that is a guilds personal preference to run those as a guild or not, but either way you should have more then enough time to fit tfb into your week even if it would take you 2 to 3 days to clear.
