Well yeah most providers use Lunar because many consider it "well trained" and don't want to go through the effort of making their own as it is very tedious, not knowing all that is possible passed Lunar.
Lunar (YoloV5s) training is easier tho.
Lunar which is based on YoloV5s is pretty old school at this point, and is also very resource intensive.
In short, Lunar (YoloV5) isn't what you should use for triggerbots, it's old school and costs too much resources to run somewhat properly.
Skyrant isn't based on Lunar nor YoloV5 in general.
Our main reason for this AI wasn't too scale the triggerbot towards other games tho, we're working on a wireless hardware aimbot + assist.
Answering to kql778 and others who have PMed me recently:
There are no plans for V5 right now, our main focus right now is improving V4 where it can be improved, and we are not looking further than that for a long time to come.
V5, 6 and future versions, are included in your V4 lifetime.
