I'm not a big fan of this strong current of powergaming culture that that the 5e community has developed, it's mirrors exactly what happened with 3.5 and Pathfinder and it sucked a whole lot of fun out of those systems (Pathfinder is such a great system for customisation and being able to express your character in mechanics, but what's the point of all that when the spirit of the community expects you build a machine as if there was prize money at stake at the end of the game?). If this was a tabletop game I'd be put off if my fellow players insisted they couldn't play a certain race or class combination because they'd have to start at 14 or 15 instead of 16 or 17.
Then again, this isn't a tabletop game. I'd have nothing against them adding options to change this for people who want to play that way. But I don't want it for the default setting.
