Temporarily retiring weapons for seasons is a good thing. It creates new meta, forces you to try new things, and resolves power creep. In YuGiOh (for tournaments), certain cards are way too powerful so they limit them or ban them outright for a few months. This forces players to think outside the box when building a deck. Every few months or so the banlist is revisited and revised. Some cards are brought back into the meta while others get benched for a while. For casual play you can use any cards you want. so think of non pinnacle activities as casual play, your weapons are still there to use when ever you want! But if you want to do high power raids or trials then youre going to need to set down your go to weapons and actually have to think about what you are going to bring into the fight. Power creep is fun until everyone is using spare rations, erentil, mind benders etc. Time to shake things up.
