A few quick comments.
I like loot. Freely admit it. I have 8 Toons that I use to raid. All that is left for me is to gather loot.
That being said, I also enjoy running quests with friends and guildies. There has been plenty of times I run raids to help others, with no need of any of the loot that drops in the raid.
I would love to see the pre reqs dropped (or some system of perma flagging, whether run them all on all difficulties or 400 faction favor, or whatever) so I can take any character I want on the raid whenever I want. I hate having to dedicate time and regiment my playing so I am ready on the right roon on the right night.
I play to have fun. I like spontaneous activites. The pre reqs plain and simple prevent that. There has been times where I plan on bring one character on a raid, only to have someone be a no show or have to cancel. Then we are scrambling to find a second cleric or fighter, or a rogue or whatever.
No pre-reqs means no worry about which character is ready. No pre-reqs means balancing parties easier.
I would like to see a pre-raid (ala the Titan) added to all raids. I know this has been said already, but I just want to voice that I am in favor of it.
Dragon Raid - Von 5 & 6 every time
Titan Raid - Forge & Core every time
Queen Raid - ADQ1 and ADQ2 every time
Reaver - Tor (Gatekeeper only, dragons would only be for first time flagging) and Sanctum every time
Abbot - Litany (to Black dragon only, rest for flagging) and chamber everytime.
While I freely admit to farming the reaver every 3 days, usually with all my character (6 runs on thrusdays and saturdays), It has always seemed wrong to be able to step right in.
Anyways, I am sure I just repeated what has been said already, but I felt it was important to add my voice to the clamor.
