And actually... meh. I don't like the system so much any more.
Reasons:
For organised factions, it is not much of a problem. You want to shoot at a base, you head to the forums and make that one ingame post that official factions would make anyway because they can't be caught not rping anyway.
But it does not work.
Why?
For a siege of a Core 1 base one needs a lot of caps. These are mainly indies.
How would I ever manage to make every one of them post some kind of rp (the link) or even to only post the first 2 lines into that thread?
This makes any attacks against any base totally impossible to do if you care about staying inside the frame of the rules. I know I would constantly spam the sieging group's channel and say. "REGISTER ON FORUMS!!! YOU MUST!!!" etc...
That's dumb.
It will result in mass-sanction against indies. You can't expect everybody to have forum account and know that rule change and find the thread. That's unrealistic.
I somehow fear that bases that would normally die fast now (in places where no one likes bases to be, e.g. blocking bases) would get the time they need to be shielded easily because the attackers waste their time, getting thigns right... and even core 1 sieges would be a real pain to oorply organise it and oorply educate everything, etc...
I think the change introduces an awful amount of oorp-ness into the process.
I do however like the general idea of making roleplay obligatory.
I don't think the approach works well enough.
I'll spend some more time thinking about what could be improved.
