Don't think it is grindy at all. In normal grindy MMOs you have to go out and do the same thing over and over again whether it is killing Ewoks or surveying for some metal it is incredibly repetitive and tedious and you only do it for the XP.
In MWO you would be spending all your time scouting, ambushing, shooting and DFAing anyway because that is the whole point of the game, they are just going to throw you some XP for being good at it as a reward and an extra feeling of progression. Many of us did the exact same thing during previous MW leagues but then we only had the warm glow of satisfaction you get from annihilating the
Draconis scum other team as a reward. Also now the sour taste of defeat and disgust will at least be accompanied by some XP to soften the blow.
EDIT: Although I see how it could start feeling a bit grindy if people let themselves get drawn into doing certain things all the time in an attempt to gain another skill level. That would just be ruining the fun for themselves, would be best to keep amount of XP and progression towards next level and all that hidden in the background so players can forget about them and enjoy the game. Then when you do get another skill it will be like a nice surprise.
