Ladder resets are announced 3-4 weeks before they happen, not several months before so you should stop worrying about one and simply play the game. Considering this is a fast progress server, you can easily gear up and enjoy both pve and pvp within a short period of time so chances are that before the new season starts you've already owned decent gear.
