It appears that deadly bash is not working on my shield skills anymore. I use Invasion a lot which I thought was the bash line. Since no passives seem to refer to any actual abilities we have by name this is a guess. I used to be able to get a few of these off which let me lock down a group of 3 and hold them while I slowly chewed through each one. Today I am out of stamina immediately. I can't hold anything anymore.
The tooltip for skills shows the full cost of a skill I think and not the actual cost after all effects are taken into account. If it costs 392stamina AFTER a 50% reduction then god help anyone who uses it without.

So my questions are:
Is deadly bash actually supposed to work on invasion ? (I thought it did but I could be wrong.) If not then what does it work on ?
Do tooltips ever actually update to take into account modifying abilities/skills/gear ?

I just discovered after 5 chain deaths on content I used to be able to do that my monitor cannot sustain 5 punches without releasing a potent aroma of overheated electronics and tripping out the houses breakers.
$400.00 later I can see again.

WTF is going on ?
