destroying the enemy Weapons Factory and Airstrip would in that case not be a penalty at all. in some cases, it would even make the enemy team better. if 100% of all vehicles were light tanks... well then GDI's screwed. i do like the idea of still buying a Buggy and Humvee for maybe an increased cost, but no more than that.
and if the Barracks or HoN gets destroyed... officer, rocket soldier and McChemtrooper only. maybe for an increased cost aswell.
I agree. Humvees and Buggys only. They could lead to some interesting tactics, like Humvees+engis assaults, and other harassing tactics using their high speed and numbers, and the ability to avoid the projectiles of the slower tanks. Maybe they should be brought to the battlefield by a transport helicopter, so it wouldn't be awkward to see the WF still working while being on fire, but that's only a visual suggestion.
I think that their price should stay the same, being the delay upon vehicle arrival the only drawback, with double price when the PP is destroyed (not realistic if brought by helicopter, as the vehicle isn't produced in the base's Weapons Factory), or make them cost double, like when the PP is destroyed, but get unaffected by a possible future PP loss, so they don't get ridiculously high prices that would make them unusable for their assured-death assault role in detriment of teamwork. We want the losing side to still be able to attack and be dangerous, not to camp in their base more efficiently with their valuable overpriced humvees. The same goes for tier 1 soldiers (rocket, officer and McChem): Double cost and unaffected by future PP loss, or same cost affected by PP status.
I would choose the double price upon production building destruction option, because there are many maps without PP.
I also think that purchasable weapons should keep their cost unaffected by the Power Plant destruction, because I have rarely seen them since beta 2, not to mention what would happen if they had doubled prices, but that's another story.
