I'm in S188 NY the level brackets I think are like 30-86, 80-8x, 87-9x and 94-95. I started to freeze at around 83, I'm now level 86 with about 62k power, and when coming against people with 20-30k power I get 16 refines every sage world battlefields. I suggest learning how the brackets work in your server bracket, and freeze accordingly. Fe. there's no point in freezing at level 70 since ur still going to fight level 86s.
