The primary goal of this weak aura is to INSTANTLY provide feedback on bomb cast as to what happens next in your rotation. If you have sufficiently high haste (~30%) then even in melee range you will be able to press another global before the mad bombardier buff is consumed (on impact). This aura will provide quick feedback regardless of situations such as naturally regenerating to 2 charges while getting a proc or getting rapid back to back procs during a red bomb.
The actual icons and indicators run on a pretty simple flowchart: If you have 2 bombs or have mad bomber buff, press bombs (it says yeet); if you have no buff, <2 charges, and red bomb active it says to FISH with kill command; If you have 0 or 1 bombs, no mad bomber, and no red bomb, it goes gray and you can go back to the standard surv rotation.
It ignores AoE and serpent sting so make sure you still carve in aoe and try to maintain SS in ST even when fishing. It also doesn't follow the bomb colors because that stuff is spaghetti and I'm dumb (lazy). Best used alongside another WFB WA rather than as a replacement if you want to see what bombs are coming up
