I'd like such a RE legacy bonus. However, I don't see a purple flood on the GTN. At least not on my server. But then again, I don't know how you define "flood" in this case.
Are 20 purples on the GTN a flood for example?
On Jedi Sentinel the purple gear is like 20:1 to the green (i.e. purple is 20 items for every 1 green). No one really sells the green or the blue because purple is better! Also the pricing isn't that much different (i.e. assuming you needed a piece and were short on cash so going for the absolute cheapest thing you could find).
Short of you being a strict F2P player that refuses to drop a single dime on the game, most everyone can use purple gear...
