Plenty of perks make great sense for legacy wide: e.g. the repair and mail droid.
Other perks feel underwhelming.
The experience perks should be way higher.
Allowing one to get +100% XP from warzones allows people that want to play Warzones to only play warzones and still have a reasonable leveling rate.
I gave this feedback when the Legacy Perks were still on the PTS but they have gone ignored.
