Achievements system to stick with the same character to get your character beter and show off what you all did and succeeded at.
I mean with get your character beter i more a way what Accolades where in City of heroes and villains when you get x number achievements done you get a small bonus.
For exsample :
achievement, Hard to kill: you are hard to kill you have been killed 1000 times and yet you still standing. (beter discription that fits CF)
achievement, Never give up!: You failed campains 100 times but you never give up.
and some more only for the idea.
But the accolade part gets active when you done x numbers of named achievements lets say the exsamples from above and 4 more.
you unlock the accolade "Stubborn" and your character gets 5% max health.
Is just a wild suggestion and idea.
