After a VERY brief look at the talents again, I see your point. It would not even feel like you’re playing the spec/class at certain levels. I can compare this to leveling an outlaw rogue currently, they’re missing a massive amount of their necessary passives until much higher levels. This makes it so that they’re only really able to build combo points to spend on slice and dice, outside of that they don’t have enough energy/time to use anything else.
I could see this being an issue in the long run if they don’t shuffle more skills around.
