lagging the most urgent problem that needs to be fix immediately . At 3.8.1, even there are huge goblin armies there were hardly lag while playing the game but at 4.0 demo when there are many troops ( but comparing to 3.8.1 there are really less troops ), even at 2 vs 2 there is a lag at mid and end game play ( when both sides started to make some troops and at 3 vs 3 and 4 vs 4 it is worse ).
