it is true as an 'edge case' that either has the potential for exploit through griefing... eg a ship flying through your firing line, and a ship, or infact more likely a group of ships, each 'ramming' the same commander under the speed limit to induce a points rise on the commander flying in to dock while keeping their points lower...
I do think these 'edge cases' would be more likely rare myself...
It's the edge cases that griefers thrive upon.
Flying through another person's line of fire takes
some skill to do properly (manoeuvre beneath them so they have less time to react to you when you boost in between them and their target) and griefers will gravitate towards an activity which requires minimum skill for maximum disruption.
If a PvE mode is created then griefers will use any exploits available to them. Especially in a mode where their target can't even shoot back.
At least right now in Open any player is capable of railgunning a suicide-sidewinder from outside the no-fire zone to stop them.
I suppose the one good thing that would result from an Open PvE mode is that all the griefers would go there where they can't be destroyed by the people they're griefing, and leave Normal Open mode.
Never underestimate the depths griefers will sink to :-(
But how to mittigate it effectively?
if the ship flying below 100 m/s in the NFZ takes no damage and therefore no points that is one way to address the issue, but I can already hear the cries of "that's not fair that should be in the mixed open mode too"...
I think that taking zero damage at low speeds should be applied everywhere to make it fair.
100 m/s is too fast to believably cause no damage, though, so maybe 50 m/s is a more 'realistic' limit?
This is part of the reason why I feel roberts suggestion is to a fair extent the best option compared to a no damage model because of the 'you gain an unfair advantage if you cannot take damage' mindset of some people
I would agree with that mindset; logically you
do gain an unfair advantage if you can't take damage in a particular mode.
So how about the points system is based on damage 'dealt', and perhaps not so much on 'ship destruction', this would negate the griefwinder with almost no hull ramming and dying causing a bounty on a player for example...
The problem I see there, is that if you remove bounties for killing a suicide-sidewinder, then you enable big ships to slow-ram and kill small ships having low hull with no penalties.
At least if a slow-boating ship took no damage as long as their speed was below the set limit, then you would stop both suicide-griefing and the free killing of new players who are limping back to the station to repair with 4% hull.
And it would be cumulative, so obviously the more damage you cause another ship the more points you lose...
It would also have a cooldown, where the license points would recover over time... and perhaps the points reduction should be only based on hull damage???
Any points system where points are assigned to both parties involved are vulnerable to exploits involving multiple attackers.
Automatically booting someone from Open PvE to Normal Open, and stopping them from returning for a certain period of time, is going to
really annoy players who are the targets of ram-to-pvp-mode griefers.
And with your idea of ships going under the speed limit = no damage, instead of that, the ship going equal to or below the speed limit would instead suffer no points reduction, still take / deal damage but no points reduced on their licence... Docking computer on, no points reduced on their licence... Report crimes against me turned off on both ships involved in the accident - no points reduced on either licence (for buckyballers)
So if I point towards you, boost, and throttle to zero, if I time it right then I'll hit you with my docking computer engaged.
It sounds like Griefer's Paradise :-(
I'm sorry, because you've put good thought into this and I don't want to come across like I'm tearing it to bits; but any solution to this issue needs to be airtight.
