starting with blind eye, quickdraw and marksman, then hardline -> assassin -> scavenger can be epic tho
I've got to MSR classes
one with sleight of hand, quickdraw and marksman. (standar sniper set up right there.) and specialist blind eye, steady aim and assasin.
and the other one I have I use Blind eye, hardline and dead slience (recon, assasin and steady aim as specialist)
never got used to the second one, but I found it works good on larger maps like Bakaraa and Outpost. Because you are less likely to meet guys round corners. and if you want to play with this set up on smaller maps I suggest replacing dead silence with steady aim. So you have better chance of noscoping someone when you meet them around corners.
