Meh. I doubt it. It was never an unfair advantage in WoW. Nothing stopped people from signing up new starter accounts for free, getting 30 days free, getting RaF rewards free, and applying extra game time to the veteran account for 30 days free.

The complainers regarding WoW and MBers was always, and still is, a weak fallacy. Blizz has 8 mil subs to tend to. Can't please everyone. Trion has considerably less subs. I would presume the increase in subs, and potential in game purchases would be greatly welcomed. IF they were to follow suit with Blizzard (no pun intended), then it will be quite some time till that happens.

Regardless, they arent doing it now, and Blizz is. So, its an easy move with no regret.
