Being on time for events seems to be a skill of it's own.
If I am late, go without me and it doesnt matter.
Been too many to describe, "We are leaving now" tends to mean "Come join us and go do your CS's and get your KIs while we wait".
I remember the old days of End game events starting at 6pm, Gather time 5:30PM. 6:30 "Sorry I am late, can you wait for me".
A few of us left a well known linkshell because we planned our own run to gain access to Sky, we got a few LS members along and ended up shouting at times to fill the party. Once the leader got on "Why didnt you make it an LS Event!!" What he actually meant was "Why cant we take all the level 30's - Snk/Invis every single one of them so they have access before they are level 75". As a result of us just doing it, we managed to get sky access in a very short amount of time. We made it clear we wasnt prepared to wait (unless we stated).
It does only take a second to /tell "Can I go get my CS's, KI's or anything else needed". Not just say CAN I COME!.
Moments like all the above is exactly why I am happy the way the game is in regards to no longer needing full parties or alliances to accomplish anything. In a full week of game play I find my self doing 6 months worth a few years back.
