At this point, I am not getting sad about not being invited, but more angry and disappointed. Honestly, what does the end of a wave announcement on twitter achieve? To me, all I get from it is that I didn't get invited and are left with a pretty nicely placed kick the nuts. This repeats itself with every wave, and I am sure a lot of you feel the same way. For those who actually got in is not going to wait for a tweet to find out, they will check their Battle.net to see if they have been invited. Really, if you cared for Overwatch at all you would check regularly anyway. So, should Blizzard announce the end of a wave? For me, I would say no.
