I just had a battle with my 1000 troops against enemy's 10,000 (i won heroic), but i wonder if the kills go into my stats, where it says the enemies killed X. So, if i have killed 98000 enemies, and i kill 10,000 more in campaign, do i get 108000 kills to my stats?
And also, the game lags a lot when you have 10,000 enemies
