Zarcath just reading all the sub trees this is what Blade Dancer gets for pvp.
Faster run, and better slide, Multiple forms of Invisibility, The ability to crouch to become invisible taking you off the radar ( Halo 2), Backstab!, Plasma grenades ( halo2), and Teleport!
That is insane stuff. Its like a Spartan from Halo if he had access to all the map buffs all the time with teleport/backstab.
Looking at the Striker, Voidwalker and they don't even compare in any aspect other then catching players bunched up in a group. That's not how FPS's work tho the better players will just pick the kill areas that have the less risk versus reward and pick off targets.
The rest of the maps would essentially have to be all small tunnels with tight rooms for your suggestion to work.,
I'm not saying you are wrong since you have access to the full game, but just on paper I'm not sure how it can work out for the other classes.
I know you can't talk much about the game, so thank you for explanation tho.
I guess we will find out when the game goes live how it will all pan out.
