1. How do I obtain rewards in the GvG Seasons?There are a couple of requirements that you need to meet to achieve these rewards, those include;
Be in a guild for 75% of the season that has achieved either Crystal, Gold, Silver or Bronze or Iron rank during the GvG season.
Have premium status active.
7. What happens if I am kicked from the guild on the last day of the season?
Your loyalty progress will not be lost, as long as you were in that guild for 75% of the season you should still be eligible for the rewards.
