Greetings all, I'm finally joining after much lurking.
While I agree with the OP that speed is valued by the Iso community, I don't feel that Goko particularly needs to prioritize speeding up the game. It already moves about as fast as I can think/read, adn I would not want it accelerated just for the sake of speed.
I do agree that more buttons would be nice, but this is more of an ease of play/idiot proofing measure than a speed one.
Having watched a number of WW's (and others) vids I find myself thinking that thinking at that speed just is not me.
That's in fact one of the main reasons that I never got involved in Iso. I tried it once, and (owning only Base and Prosperity at the time) while trying to figure out what the cards in the kingdom did, started getting snarky comments about how slow I was being after less than 30 seconds or so. I just quit and never went back.
I have no problem with the pace of the game on Goko, and it seems that by and large other people don't complain unless there is a clear delay. I've only ever had complaints when there is a legitimate lag/freezing problem with the server.
I'd hate for Goko to move in the direction of players valuing speed to the point of being rude to a player who may have many fewer games experience just because they are taking more time.
