I need my guild in Bronze next round, even though we made golden performance this time, a rest is needed at this time.
To leave use in Gold is not fair to all conserned !
You are much, much better off coming in last in gold league than first in Copper (there is no bronze).
Last in gold gives everyone 47 fragments, and 195K power to the guild.
First in Copper gives everyone 13 fragments and 13K power to the guild.
Oh, and the personal rewards are better too.
Take the extra fragments guild power and rewards while you can!
If you need a rest, then rest. Play at the level you are comfortable with and can sustain. If you come in near the bottom, so what? If you continue to place near the bottom, you will be moved down a level (gold to silver first, in your case). If you still don't do well, you will move down to Copper, but it might take a few seasons. In the mean time, enjoy getting the rewards that come with being in a higher league
