Yes, it is difficult to control units and the game is very laggy. Most matches, players leave or are disconnected. I started having issues where I was stuck on the load screen and had to alt f4 out. I've been stuck at the "warm up" part of Blitz matches and unable to move my camera or control my units. I have leveled up to rank 5 at least 6 times now and each time I have received a non existent card pack. If a player(s) leave or are disconnected, it is near impossible to win, as you don't get their units, resources or an increased energy rate. There is also no way to quit or surrender the match, at least esc does not bring up a menu. My game is set to be in full screen mode. Every time I launch it, it is in windowed mode but the cursor needs to float an inch below whatever I am attempting to click on. The only way to fix this, is to set it to windowed mode and then back to full screen mode. There is no Apply Settings button so you have to back out to save the selection each time.
