I don't really see a point in bringing back the races plugin. In my opinion it was very limited on what you could do, and allowed for nearly zero creativity. Look at Vampires (Which, yes, I know, are not a race.), with the new bloodlines being created, there are too many variants for solely the old vampire plugin to work. Some vampires don't take damage in the sun, making the ability to adjust that while keeping the jump boost and speed boost makes the traits become a much better alternative to the races. With ousting the old negatives, old ones can be issued in and interchanged. Take the Kleinfolk and Q'urebo for example, while being exceptionally fast and having numerous abilities, with the races plugin they would have had to either imagine in RP, or carry around speed pots to generate the effect for them; a waste of materials and time. Bringing races back makes little sense, seeing as the traits can do all the races did, with so much more.

As for the PVP aspect, I am not much of a PVPer, and this is just what I view from my friends who do PVP. The traits plugin allows people to excel in some categories, like axes, while maybe being weak to swords. This, in my opinion, evens out the PVP side of things very easily depending on how it is done. Races limited what you could do and what your strengths were, while traits allow customized builds and a constant drive to find a 'perfect build' to outwit your opponents. It makes it rather something of strategy, rather than just taking a buff against damage or taking one to deal more.
