I didnt do this in the Beta (wasnt worth it with only one week), but when 2142 arrives I think I'm gonna unlock everything using four different soldiers, one for each kit. There are 8 unlocks for each kit, so I can get everything in about 4000 points. Then I can go back and add grenades and squad leader stuff and I'm done, everything unlocked in a few weeks.
The only disadvantage is that changing kit mid-round gives you no unlocks, but compared with doing away hundreds of hours needed to get them it seems pointless.
