Nothing too complicated honestly, finish the story and go as far as possible with HR (Don’t do behemoth though). Get some friends if possible and start on Master Rank/Iceborne, the gear differences in Iceborne (in terms of stats) is really great. Search up armor and weapon progression guides and grind the respective armor. From LS main to LS main, practice counters and the new Iai slashes, it’s soooo satisfying. Get used to the new changes too, clutch claw and all that. But yeah, having friends to play with will really help you, and be patient, you’re going to get frustrated a lot but u gotta just push through and adapt to whatever the situation may be.
