I would suggest 2 improvements:
1. This is the ability to collect FPs up to 500, not 100. It is very inconvenient when the fps collection is more than 900, to go back and forth.
2. As for the GvG battles on the All Ages map, the army filter by era always goes to the All Ages tab. For example I want to fight only with the SAAB troops and I was able to quickly select them
