"main problem" - I would rather say you listed some symptoms..
"*do a black knight." - Really? What's the problem here? What obsticle hinder lvl46+ members from getting it done?
"*do 2 adventures." - How hard is it to do DP?
"*with them above maybe some totally ignore/to heavy to make." - Seems like bad co-operation.
"*(not a problem but becomes with guild quests) members play at their own pace and be away from tso for a while/days." - this shouldn't be a problem as it's not everyone needed to do their GQ, but only 80%; thou GQ is given as waiting GQ to active players atm and will get activated later for all of those players...even though some of them had been flagged as inactive. The latter is the main problem here.
"*(just a feeling) for some members the gq becomes the definition of a guild.
Its not and specially not with the current poorly mono designed quests." - So what else is there? You really don't need to be in a guild if you just want to chat or do advs..
Also, have you compared those "2 advs-GQ"s with 'Songs of Seasons' there all members from 36 to 50 have to do 1 adv? Did you find the latter to be easily done?
