From John’s OP.
This suggestion doesn’t really fall under scoring specifically, but would both affect and be affecting by score.
Add meta events that are directly triggered by a combination of score and population that can affect walls, supply, or anything meaningful to WvW success. GW2 has very heavily used random events in PvE to great success, why not use them to help balance WvW? These events are more likely to occur against a server with a more substantial lead as well as against a server with more players online. This would give the servers ahead something to do and give the servers behind an chance to recover and come back. All said and done, this would likely be a substantial amount of work and could be very difficult to implement and balance, but is also extremely versatile and rewarding to players of all sides that want fun and not just for easy wins. It would help alleviate population imbalance, snowballing, loot rewards, and definitely stagnation.
The downside is that this essentially implements more PvE into WvW, adding NPCs to even out the player difference, BUT there would still be player enemies whereas PvE does not, and this would be another ‘tool’ to consider, use, and leverage for the little guy. Some of these events could be friendly to one or more colors while some could be hostile to all but with a specific goal in mind.
Now, before you go clipping a part of my post to discount the idea, this is meant for balance and improvement. If green is 100k more points (or more) tin the lead, has double the players than the other two servers combined at the time, and has had SMC fully upgraded for three day straight, why couldn’t there be monsters attacking the castle? It would divert their attention and force them to split their forces more and give everyone a better chance to make a difference for their server. If implemented and balanced well, it has huge potential and could easily be changed and flavored for different seasons, holidays, or whatever the devs want!
Here are some examples off the top of my head:
A legendary giant attacks SMC, damaging walls with punches and stomps. It is indiscriminate, also attacking anything nearby, but primarily focusing on the walls. If it manages to cap SMC by itself, it turns neutral again.
Krait emerge from the depths of a borderland center (where they were before bloodlust!) and attack water gate of Bay or Garrison. Once they breach outer, they plunder the supply and leave.
The centaurs and skritt that currently attack the north camps of a borderland now rush in to steal supply, lowering the maximum supply the camp can hold until it is flipped and/or another event is completed to get it back!
The workers rebel! They refuse to continue an upgrade and instead take up arms against the guards! The guards will have difficulty fighting their own and will need help to get them back to work!
A largely undefended keep of a low population server is under siege! Ascalonian ghosts appear to defend their ancestral fort!
For Halloween, the Giant could be replaced by the Mad King himself! Add an aoe fear effect and minions! Add story and background to WvW! Put in whatever would be fun and productive! But whatever you do, don’t get too caught up in the little things, but keep the focus on balance!
