If they really want TF to take off they need to be more original, they're already half way there with the parkourish movements but you need to scrap the perk systems. Too many shooters use 2-3 perks for a load out and in my mind that's not very original anymore. So to replace the perks incorporate a system where as a pilot you have multiple suits you can choose from (For example: Mechanic, Recon, Anti-Titan, Ranger) each with there own styles of play and instead of perks you add a skill tree and as you play as a certain suit you progress and earn points to spend or your skill tree. While you may say skill trees aren't original I'd agree but we haven't seen anything like it in a FPS before.
