That's too bad, the dull pain behavior was just what the regen set needed. A way to counter the effect of low defense on a Stalker signiture abilities.
I've read this thread about Leary 3 times now... the one commonality is that everyone who has reported getting Leary missions has exactly one unused respec. If you have 2 unused respecs it doesn't work, if you have used any of your respecs it doesn't work. If anyone has exactly one unused respec and still doesn't get the Leary missions.. please post.
One thing that I saw brought up back in the day... but no-one seems to have mentioned yet is that there seems to be a negitive effect to TOO much ACC. I haven't done much testing, but someone who wants to test it out can go find a bunch of blue minions, eat a tray full of yellows and go to town... maybe even with ACC boosting powers running.
