well 10 exp is better than 100 exp still its hard to get the synths i also noticed each rank gives a static amount of exp r1=1 exp 2=2 etc. so im guessing tnls are still low highest rank is still 10 atm wonder if it goes higher. Also when u achieved rank 2 did u get a new achievement? People should also look into the achievements to find out the cap. I got a feeling back wings are at the highest level.
