In my opinion and experience, the durability and strength of vehicles should be determined by their cost to pull. The order should be as such: MBTs/ Liberators/ Galaxies -450 nanites = strongest or most durable Lightnings/ ESFs -350 Nanites = middle of the road, either very powerful or moderately tough Sunderers -200 Nanites = Really tough or really powerful, not both (and modules determine it here) Harasser -150 Nanites = Glass cannon (but seems to also be almost as tough as a Lightning) Flash - 75 Nanites = why are you driving this thing? The two sources of contention for harassers is first they can equip weapons that where meant for MBTs, and these weapons are extremely powerful (Saron, Vulcan, Enforcer). Encountering these on a MBT is already a bad day, but you encounter them on a zippy vehicle like the Harasser? Its hell on earth. The second issue is the Harasser is actually really hard to kill. You can fire 2 AP tank rounds into them and they'll only be smoking (which is about 30-50% hp). If you miss a single shot on a Lightning and it is a Vulcan Harasser, you're dead. Whatever is done to fix these awful things, it should either take away MBT secondary guns away and put them on something like a Lightning OR nerf their durability so getting hit by two tank rounds sets them on fire; Composite Armor would allow them to take 3 tank rounds before being on fire. I could see giving those secondary guns to Lightnings as they're a bit slower but still fast in their own right.
