Hey bro,
Did a full diagnostic on the Ambush card.
If killing a enemy out right from mele kill from the front, will not jive you back ULT recharge. However if you hit them from the front and they bleed out then it does.
However, this does now not work on Juvies, leeches (never did tbh) and now Imagos.
And lastly, executions from behind, while DBNO will also count correctly. This also includes the swift kick with the B button. You just need to get behind them.
So here is my guess as to what happened. They fixed the DBNO issue where before executing at this time was hit or miss. But in doing so messed up the Bleed recharge from Ambush on non DBNO swarm dudes.
And last thing. If running the Claw card with Ambush and Flank, there is some weird recharge thing happening where you are getting ULT back super fast. So here is what you do. Look for Scion type or bosses that are slow, like the carrier as an example, if there is an option to get behind them safely, shoot them for about 5 secs or so but where you are just out of grabbing range. When you do this your ULT recharge is crazy fast. And you then finish them with ULT.
One final thing. Thrill of the hunt is pretty much broken now, so I wouldn’t even use it at this point.
I’m fleshing out a hybrid build for this class and will relay to all soon.
Cheers!
