I agree that making PvP the best way to rise in power is a great idea.
I just don't know how to keep alts and alliances from using this too their advantage and constantly just attacking eachothers' fleets to rise in power in an unlimited fashion.
In order to achieve a balance between gains in PvP and stopping buddy / alt attacks for gains, there needs to be more destruction to the enemy then the gain of the attacker. Last but not least, the defender needs to be able to play after the attack, so I'm thinking salvage both ways here...
Now, let's take a normal PvP attack where the defender is utterly powned
Attacker loss: 5% of the armada
Defender loss: 90% of the armada.
Now we apply salvage on both parts to ensure further PvP in the future between the two parties.
Attacker gets 25% of the salvage on defender losses (items & credits), defender gets 55% from salvaging own fleets in battle (credits), 20% is lost in the fire.
Attacker gets items, defender gets credits from selling the scrap metal
Attacker losses:
-> if attacker is successful, the attacker will salvage 55% of the ships lost (credits), defender will salvage 25% of attacker losses (credits), 20% is lost.
-> if attacker fails, the defender salvages 55% (credits), the attacker 25% (credits), 20% is lost.
Of course this will have to take into account resupply bonuses, so commanders with more resupply bonus will get less credits salvage, but the idea is good I think...
