I actually had an idea I was going to put in later, when you master your subclass you can lock it like in the beta but you have three special perks to choose from when locking it. For example, I mastered Bladedancer on my Hunter I can choose either (Dive to short-Blink), (Increase the damage of consecutive hits with Arc-Blade), or (Additional Training Focused strictly on Agility). You know things like that, pretty much made up all of them on the spot except Dive to Blink which is my favorite Idea ever. I'm thinking of giving the Solar Titan Falcon Kick when you dive XD. I also did an old thread about adding in a fourth row of perks to each subclass since I too feel like I'm very limited in my subclass specialization. I did scrap a lot of those ideas like the Titan Bubble following the caster or being able to shoot out of the Bubble because that is a bit game breaking.
