I have seen the discussion before many many times, so what i dont get is why is it so difficutlt for the developers to add a ‘‘ready’’ timer in the battleground?
Everyone can vote for being ready so we can move on with the game, the amount of times everyone is just sitting around waiting for 40+ seconds is insane, its a massive waste of everyone’s time.
ESPECIALLY in the start, sooo much time just waiting.
PLEASE add this. 
While it’s true that it can be useful at the start, later on I can imagine it almost never being pressed when people really get their builds going and they start to scale.
That being said, I do agree, it should be added.
The algorythm decides the outcome, the moment the combat phase begins, sometimes, in very slow games, it moves behind. Ready timer, will be just a placebo. A fake threatment of the problem, giving the illusion something is diferent…
There are technical issues at work i.e. latency between countries.
You may laugh at this but I recently played a game of BG Duos where my combat was just starting and a Question mark appeared on my portal, meaning that on my team mates PC the combat round had already ended and he was asking if I wanted a minion in his tavern.
That’s 30 - 60 seconds right there as I was playing Undead.
