I used one of the four I had on release day and still regret it lol.

Tactical insertion is what I used my first token on.  I feel naked without them.

MK14.  I used to love the gun at the time.  I made very good use of it for the next couple prestiges, so it wasn't a complete loss.  But I haven't used it in a really long time.  I don't even have it on any of my custom classes anymore.  I got good enough with the ACR on large maps that the MK14 just didn't much sense anymore given its huge disadvantage at close and medium ranges.

Close calls: Dead silence, portable radar, and FAD.

nothing
I have -2143 tokens 99 days of double xp and 99 days gun xp #winning

I spent my first token on the T95... don't even use it now cos of the shame factor .. also wasted one on the Deagle... a fool and his tokens are easily parted... no regrets over the MP7 or the MSR though
