You can only invest up to 10 points in an ability, though probably can get more from item bonuses. Regardless, leadership is damn good, even with its range deficiency. IMO it's impossible to balance with its current numbers. A 50% damage reduction on all allies within range? No wonder it has to be 5m. It's flat out broken in my bard mod with 8m imo. Sure, it doesn't buff the leader but just make your leader fairly tanky through other means, and you'll be good.
Retribution is very good too, especially on a tank. Hopefully we'll see more ways to direct enemy attacks towards you, but even now, you can accomplish a lot with good positioning.
Perseverance is garbage though. But again, it's kind of a tough thing to balance since if it was too good, it'd make a character extremely tanky and semi-immune to most CC. I think it should have a smaller effect but proc off a far wider set of statuses.
