Your character would become reduced in levels along with gear. My belief is that bracket will stay the same, but your level Is dropped after launch or prepatch. If i remember corectly, the new zone to lvl for starters is 1-10? Or you can stick to original starter zone. After the starter zone, You can get new gear from Vanilla to Legion zones (maybe even bfa)Title says it, but do we have any clue what might happen to 19s with the level squish that is coming up.
TrooI'm also fairly confident level 1s will remain level 1.
