Slow GNB (2.50 GCD) is the current (6.28) Meta for high rank parsers in Gunbreaker. It caters to the current BiS (Abyssos Gear) that lacks the skill speed substats that Gunbreaker usually needs but it still have the best base stats & Crit – Direct Hit Rate
Contrary to popular belief, it is much easier to play – with only 8 GCD inside No Mercy and less rotation variation than your normal faster Gunbreaker. Yet at the same time it punishes drifting your skills (Gnashing Fang/ No Mercy) more.
In this guide I try to break down the rotation to it’s simplest fundamentals and run you through a full 8 minute rotation of it
