OFB-8

That's exactly the point – the timer accumulates at first. But when it's time for a long, strategic game with multiple heroes, focusing on control and building up power, it starts to decrease rapidly because, at this stage, turns of 20-30 minutes are not uncommon. Late-game play is, of course, one of the components of the game, but a short timer severely limits it. Ah, if only there was a timer like (6+2n)+8+1, where n is the week number).

I understand that there are slow players and those who deliberately slow down the game and get on people's nerves, but ideally, if two respectable players are playing, I wouldn't want the outcome of the game to be influenced by timer-related stress.
