Great ideas!
Would love to unlock a class specific character for reaching lvl 10. I love to play sharp and none of the characters make me feel like a bada** sharp.
Not sure why everyone is worried about it being too much....I mean the entire point of gaining lvl 7 through 10 is to give us something to work towards and to broadcast to the community how good we are at a certain perk. I say go big, lvl 6 can't be too insane because you need it to gain that extra bit of power, but these are different.
I have 2200 hours in this game and have 3xlvl 6 for every perk....72,000 hs for sharp. I would want lvl 10 to be difficulty to earn not something a few months of HoE would get me. Or else we would all get to level 10 prestige and this conversation would start all over again.
gaining lvl 10 isn't for your average player and shouldn't be it should be for those of us that having been playing this game for years and don't plan on stopping

As things stand we see a lvl 6 perk and have no idea of their skill level, but if we see someone join a server and have a lvl 10 support, im throwing them dosh because I know he/she is a bada**
