It would be nice if random draft game's time limit was adjustable based on PSR or player level. A higher XP player knowns which heroes to use and thus doesn't need as much time as a lower level player. Instead of the static 20 second time limit, make it dynamic or a "upon game creation" type of setting (maybe defaulting to 20 seconds).
If this isn't doable in the short term, maybe increase the timer to 35 seconds as this should give you a chance to recognize all the hero faces AND make a decision.
And makes sense in games with more experienced player for sure. But if others aren't experienced or don't recognize all the faces, then 20 seconds can blow by to and inexperienced player.
I think the random draft is a great game style to force hero diversity. I'd just like to see the ability to adjust it from 20s to something bigger. whether it be dynamic or a per-game setting doesn't matter to me.
