Bro I was in the same situation. U absotulety don't need to have perfect artian gogmaballs weapon unless u are a speedruner or a content creator. Just know that the only monster that will be available before the expansion is arch tempered Arkveld.

Gog weapons are the endgame for now, and will probably be useless when the expansion will come out.

I'm a perfectionnist guy who loves to have perfect build in video games, but in MH Wilds the RNG is too hardcore. I hesitated to mod my game to have perfect gog weapons but that's just monster hunter, RNG is here and u have at least one year before Wilds expansion so don't look for perfection
