I believe the best reply to these threads is the tagline that a forum vet once had many years ago which read:
"Nerf your class, buff mine"
It's like a diabolical circle of complaints as you read the threads flowing into one another: Eles want thief nerfed>Thief wants WB nerfed>Ranger wants Engineer nerfed (or anything with reflect)>Guardian wants Chrono nerfed>Warrior wants ele nerfed.....etc
Given the poor state that WvW balance is apparently in, it's clear Anet don't take these threads in to consideration when making their adjustments. Probably for the best.
Still, it makes for amusing reading on a wet, cold afternoon.
