I'll definitely be buying the Rank 1 Speeder Piloting for all my alts. Rank 2 and 3 is a bit expensive so I'll probably pass on those.
I wish those got unlocked by default when you reach level giving you speeder anyway. Or all those perks to get their cost decreased according to profit they give you. So faster exp won't cost same character that is already lvl 40 as character lvl10. Thing is, while I'm completionist and would like to see(at least on my main) all candles light up, it'll be hard for me to justify spending few millions for this, where there is no profit at all other than lighting it up.
