My 2011 had issue going into first gear, but it didn't matter what gear I tried to massage it into before trying first, whether it was just left of center or whatever. It just refused to go into first gear. It got worse and worse as time went on. And of course when your light just turned green and there are four cars behind you, the last thing you want is to be "that guy" who can't drive a stick and is stuck at the light. Often I would just get flustered and mash it into first gear. Looking back, that was probably unwise.
Now that I have the 2016 and can be sure all maintenance is done from here on out, I'll keep an eye out for first signs of first gear becoming stubborn. But I don't think you should have to change how you've always shifted a manual because first gear gets finicky with age. It is probably a problem that develops over time.
