I agree with this thread in some points. The flag hidding/sinking is somehow frustrating for owners and so for raiders. I think the laptop hack is way more real, the thing is that nobody will use a laptop/remove it so it won't be hacked. One posibility would be to need a laptop installed in base to upgrade it, and if you remove it you lose protection (just as if the flag was missing). The rewards from hacking the laptop could be money/respect from territory owners, some of the vehicles/safes in the base radius get unlocked.
Just throwing some ideas here, the flag steal thing was a nice addition, but maybe it could be funnier/riskier.
Sorry for my english.
