Why not a defensive ap compertion, it's very hard to get and very expensive to get lol,
with unit rebuild rates😔

Its hard to come up with a compertion that could be won by any player willing to put the effort in.
Say the number of battle wins defence and attack, wins in a set time adjusted buy commander numbers?

Best kill to commander ratio so the minimum units and commander to get the highest unit kill adjusted for commander level. Against npc targets.

Fastest attack rate in a very limited time, say 5 mins or less but within a 24hr time this is adjusted by commander numbers and number of bases a player has. So a player must organise multi hits to take place within the 5 mins of time but any time within the 24 hrs he can retry as often as he wants. As distance to target is not the problem but timing of the attacks to hit within the 5 min time to max their score the game would have to record attacks then find the players peak at the end of the compertion or every few hours. All this against npc bases
It could just be the number of attacks that take place and the player with the highest cluster of attacks in the shortest time wins. Or include unit value killed.
