What is this fascination with denying an entire country radar anyhow? I don't get it.... (only purpose is to cause GRIEF, and currently it has such a negative impact on finding ONLINE ACTION that is important to healthy main arena numbers).
There! someone said it out loud: "GRIEF".
That is the only incentive to fly HQ raids. It is not even strategy - those that play the strategy game know to hit the city and the AAA/ammo/radar factories, not HQ. I dont recall any case in which the destruction of HQ was followed by the opposing country rolling over our bases. I bet 90% of the players on the other countries do not even know that our HQ is down. In almost all cases, once HQ is finally back up after 30 minutes or so (with resupply) the strategic situation is exactly as it was when HQ went down.
Score? HQ raids are not good for score.
Perks? HQ raids are poor fields for perk farming.
Challenge? if you want challenge you do not fly at 30k. NOE, maybe.
Role playing? right... and bail out after bombing.
Strategy? worthless, see above.
After eliminating all other possibilities, what ever is left must be the truth - grief. The #1 motivational reason in MMO's.
