Doubling the recharge time on Sting of the Wasp kills one of my characters. I have an AR/ Ninja blaster who does a fair bit of melee. I slotted his sword attacks to go as fast as possible. They were still a bit slow, but manageable. Now, not so much. I will therefore ask again that the fighting pool be customizable to show different types of attacks, including swords. I wouldn't even care if the type of damage didn't match up. I just want to swing my sword....
On the other hand, adding stances was a great idea and saved me from having to respec one of my guys. I always kept him in Beast Run mode because it suited him, but recently took Combat Jumping, which negates it. I was going to respec to remove CJ, but now I don't have to.
Beyond that, I really like to see new missions being added. That, for me personally, is one of the most important things to focus on.
