I guess since the people who responded have only been playing since patch 1.2, I need to explain something to them. Hunker Down used to provide immunity to everything. Now it doesn't. There was no patch note about it being rebalanced to only work when it feels like it, just a core ability that now ceases to function in a way that makes it useful. 1.2 Even added a new talent that makes you take less aoe damage while in HD, yet virtually every CC in the game now has a chance to knock you out. The inconsistency is what is most embarrassing, because being immune to everything seems a lot easier to code than being immune to some things. Furthermore....it used to work perfectly. Now it is broken. It has stayed broken too long and I don't mind saying so.

I literally can't imagine an easier ability to code, yet for over a month(possibly more) the one ability that makes this class worth playing is completely worthless. I have counted at least a dozen abilities in PvP that knock me out of Hunker Down, often within the first few seconds. If you can't fix this ability, please quit the video game business and go back to making medical supplies.
