I leveled up Armstech to 400. I was around level 200 when I realized that there was no point, but it was too late and I decided that there was no going back.
ALL barrels, blasters, snipers, etc. can easily be attained else-where. For a small price of 10-14 commendations, you can buy a better/just-as-good item. And I really don't see how they can re-do the system any time soon... Seems like a fail to me.
But hey other than that, I have no complaints and I'm loving the game.
