I don’t see a problem here. If I’m not mistaken, it looks to me Robby is out of range, and manolis is avoiding Robby’s death range. At that point in the battle, it’s a battle of will.
In regards to pusher builds:
I fought several pushers using the same tactics against me (namely, Bobson). At first, I was upset at those pushers who avoided death by staying out of my weapons’ range. I'd end my turn at the very last second on the countdown timer to get back at them.
Then later, I realized, damn, I want those pusher builds. So, I can do the same thing, lol. After all, pusher builds are still legit builds.
Later, I started typing “gg” to Bobson, and ending my turns quickly. Bobson returned by typing “gg” to me as well. I could be wrong; I felt Bobson respected me when I started typing “gg” to him. I certainly felt respect for his intelligent pusher builds, hence the reason I typed “gg” to him.
With everything said, and in spite of the situation being a bit different from a pusher build, it’s a legit stalemate with the loser hitting the quit button first. I don’t see the reason for the fuss if people simply hit the quit button, so they can move on to the next match.
