Hmm... I was thinking that it would be wise to open all the reward boxes and store the energy once it reached 30/30 either after the season ends or when you know you are deep enough into rank 1 that you won't feel like you must answer any new fights that could potentially relegate you back to Rank 2 (assuming you want the EOS reward). So that way, when next season starts, you'd start off with the max 30 energy + 200 energy (10 energy each from the 20 boxes) + 15 energy (per fighter showcase completed) + any other energy that you get from the daily login rewards.
