Trading heat maps are aggregated over what period?
24 hours, or one tick if I remember right.
Collating DPS of opposing ships would reward players if they were in the same system as those camping in their DPS optimised ships - with no guarantee that they'd actually instance with them nor that the pilots in those ships would actually pose a threat.
But thats the idea: potentially you might not meet anyone else, but you are still risking your neck going to those places anyway because FD record each ship. In each case you took the chance that people in solo did not, along with the chance of meeting an NPC.
Hence the counter proposal to weight Open merits according to actual losses due to PvP - something for something, not something for nothing.
Its an interesting idea, but I'm not sure how it would work in Powerplay as it is, there are a lot of inconsistencies and angles to think about. For example:
Bigger powers attacking smaller ones- would relative size of power be considered?
Some powers being in combat all the time, while others hardly at all.
You have 11 powers with some allied / neutral- would you have weighting per grouping of powers or per power?
Your weighting idea is essentially hazard pay, but the temptation to drop to solo for 100% and lack of opposition is still there. The difference would have to be much more.
Is it exploitable? Console owners have almost infinite commander profiles and could plump up figures with the free merits (and that money flows like water these days).
You are effectively rewarding failure, as the more you die the more merits are worth. Part of me finds that counter intuitive, i.e. the more you hurt your enemy the stronger they get as they have danger pay (although it could balance out). In such a case it would
discourage killing opposition forces.
Ironically your idea would work best in reverse, where the attacker is rewarded- just like war aces you get a multiplier the more kill marks you have. In a double irony that would work best in an Open only context.
