Savage is a lot of hard work with low rewards, no wonder people aren't eager to do it.
I would like to see a little social experiment. How much would the raiding population change were all the weekly restrictions removed? Making the savage the only place where you could gear up in the best ilvl for several patches, and allowing players the freedom of movement between the groups.
Right now the amount of raid time we have depends on other 7 people in the static - if someone clears it with a different group the static gets punished and you probably kicked. I don't think this is helping the clear rates and overall appeal of the hard content. There are times when I have nothing better to do, I could be helping people with clears, but nope, the raid day is the next day so you can't touch it today... this is seriously annoying, because it discourages the raiding community to help the newbies.
