i actually need to get something straight
what exactly is the definition of metagame?

anyway, i have been hearing ranting on how two vs two will be the new wave of the metagame. I am wondering on what basis this presumption is based (evidence). Some have suggested that r/s is actually quite revolved around 2v2 battling, yet i see that the games offer little in game training for the new sport. What are some of the various new combos strategies for 2v2?
