I am really missing CS:GO and LAN tournaments. 
Not just for CS;GO but also for Dota 2.But there is nothing to miss, we have online tournaments that you can enjoy to watch the live stream or replays. I mostly watch the replays if I miss a game.
I do the same. Can you tell what team in CS:GO is the strongest and most promising for you?
The rankings in CS:GO always change and there is no team that can maintain on the first position for a very long time. BIG is definitely one of the most promising teams right now, being #1 in the world after a couple months ago they weren't even in the Top 10. Complexity is also a very promising team that rise in the last couple of months reaching Top 10.
