Showdown thoughts
First I would like to say that I have been looking forward to this game mode for a while and it is every bit as intense as I thought it would be.
I have played around 20 1v1 and ~30 2v2 games so far and out of all of those I've had maybe 3 games that actually went to 100cs, and only one of which where we downed a turret. Most of the time first blood is what determines the outcome of the match.
I've had some really good and really bad team mates as per usually but when this comes to live I definitely won't be playing 2v2 with pugs anymore.
The only complaint I have is that the character selection timer could be a little longer, while the pregame (post character-selection) timer is far too long. No one needs 1 minute to change a rune page and masteries.
