I just wish ArenaNet would stop considering a Sledgehammer an appropriate tool for adjusting the game balance and that they would properly test/evaluate changes before releasing them or better even talking about them.
The latter is the main issue here. It is more than obvious by now that only a tiny fraction of ArenaNet employees are actually playing/knowing their game well enough to know/predict how changes will affect their game. And since there are no public test servers, the live servers are pretty much in beta all the time.
Just look at the Scourge Yo-Yo over the last 2 months.
