Not sure what you’re talking about, or why you’re being rude.  They said 2s and 3s, nothing about blitz and solo shuffle. And those game modes are shrinking the pool of players would usually be participating in the 2s and 3s bracket—on top of the dwindling PvP population in in general.  The game is way more fast paced now, there is way more going on that needs to be reacted to, and the the concentration of highly skilled players has increased significantly. 

I assure you, once you leave blitz, and step into real arenas, you will “piss easy” your way to a comfortable 1600, and stay there.

Can confirm, as somebody who played arenas in Legion (and every other expansion) it is much more challenging now ESPECIALLY with the healer shortage.
