Here's the thing though, if you make so players who have played for longer have a distinct and continual advantage over those who don't, you will never see new players. I started around HW's release. Why would I continue playing if no matter what I do, someone from launch is ahead of me not because of their individual skill, but because they picked up the game before I did?
In what way are you "always behind" the older players as a new player? If you start the game off right now and play it on a consistent basis you can get through 2.0 to Heavensward in around a month or two depending on how many hours you can invest. By the time you get through HW you should be in whatever the most current patch is and then you can gear up to the latest gear. I have a friend who started around March this year and is already i230 and has a few Classes at Lv.60 now.
