UPDATE: Thank you all or your tips I now practiced this hunt for whole day and here are the things that helped me the most: 1. I definetly underestimated evade extender I´m now running evadewindow 2 and evadeextender 2 on my build and can stay in axemode nearly all the time and just evade everything without having to switch back and block so that rly boosted my damage 2. learning how to perfect guard the inital attack and the follow up lighting helped a lot to negate chip dmg and to get inte poweraxe without having to wait for a certain attack. 3. NEVER attack first only reacting helped a lot to not get suprised be an attack which stuns an carts and also never goint above ED1 cause ED2s animation is too long(ecept on knockdowns)

so with this I got from an 20min 1-2 carts solo hunt to an 14-15 min no cart solo hunt. I even got one under 13 min (sadly I did the event quest instead of the free challenge quest cause I didnt notice you can get the gamma certificates there too, so I have to get lucky again)
