Starting GU

I'm a 5th fleeter technically. I got mon hun world at release but bounced off it. Until it clicked. I now have 500 hours on World, 400 on Rise and 800 on Wilds. I have exclusively played charge blade in all three games. (I do have 100 hours on HH on wilds.)

I decided to pick up Generations Ultimate. What should I expect jumping in? Any tips or recommendations? I know theres no savage axe so thats gonna be different. Any advice is welcome.
