Its really not anyones fault, this shit has happened to a lot of guilds in this game. Endgame just doesn't have a concise Point A to Point B slow burn path anymore and as a result, people just stop attending raids when they either get A) hard, or B) unfruitful for themselves.
25 man raiding for the all convenience it brought to the raiding situation (they used to be 40 for those that don't know), really screwed up the ability for guilds to over stock players and have steady alternates to run whatever instances were necessary for overall guild progression.
I have had an urge to play again recently, but I look at what I used to love to do (Leading Raids) and I feel nothing but pure apathy about it.
Also the gearing up system is just so bizarre now with the Arena gear.
