So, I use a PS3 controller on my PC, and the game thinks it's an XBox controller (which I really don't care about, and not what this post is about). But I've been trying to change some of the keybinds because of the PS3 controller layout.
On an XBox controller the Block and Attack are Left and Right trigger, which are the same as L2 and R2 for PS3. But It feels awkward using those as my main attack/block buttons, so I want to switch them to L1/R1 (or Left and Right Button/Bumper for XBox). Now, changing those are fine, and I just switch the two abilities that were on L1/R1 to L2/R2. But when I try to change the Interrupt action (originally set as "Hold LT + RT") to "Hold LB + RB", it doesn't work. It just changes it to LB + RB which is set as my Ultimate. For some reason it allows me to set something as "Hold LT + RT", but not "Hold LB + RB". I press and hold LB (or L1 on my controller) and it shows up on screen as "Hold LB" as the keybind, but as soon as I press RB (R1) it just changes the bind to LB + RB even though I'm still holding down the LB.
