Level freeze or don't. it's really your call.

Yes delaying the grind does give you an edge but if you're in an older server there will always be a p2w level freezer that vastly out-powers you... in fact as a few have said 9+ in most tiers, but that still isn't a bad thing, actually while you're at it why not WOF farm, all you have to do is not play for weeks at a time and reap the benefits now that sun and moon scrolls allow the classic freeze items to be bought. Figure if you cycle freeze and wof farming from lvl 32 on a fresh server it'll take approx 8 months to hit lvl 85 and if the farmed resources are used appropriately you can easily grind power with virtually no effort out of intentionally doing everything you can to not progress the game. Done proper you will still be in the zabuza arc once you actually start playing again, which in turn is where the rubber-banding begins. you will never be toppest kek but you can abuse this to farm coupons, scrolls, sun n moon mats indefinitely, with 40k coupons you can get both shisui and jounin minato (or shisui + anbu itachi @32k)

Or alternatively you can just play, communicate with other players, have fun with the community and even have fun hazing players... I mean this is supposed to be an mmo d@mnit it's not just a min max spreadsheet, this is supposed to be a game you play not a game that doubles as an accounting career.

But alas you be you, if you derive joy out of ev and iv training pokemon for the perfect stats for months... even years then you should participate in freezing, if your the type that just picked up the latest title to enjoy a campaign and maybe casual battles with friends dont freeze. Either way theres hundreds that do whichever path you take that can help you or even become a new friend.
