The OP complains about people continue to farm pirates because of an “imbalance” that they spawn more champs. And they even do pirate events even if no more pirates need to be killed.
The pirates spawning too much champs will probably be fixed in the coming days.
Reason here is that most pirates start already at veteran level . Because of this they upgrade the level easier when more people come. Instead of three tiers normal -> veteran -> champs (plus hardcoded and random champs) the pirates go directly from veteran to champ instead of vetaran -> stay veteran -> become champ.
Basically scaling for pirates is bugged.
The pirates are just intended to be harder – not better loot by going to champs right away when more than X people are there. It should be same for minions as for pirates.
This is basically the same bug as in the farm pavillion when the centaurs spawned too much champs because they started also with veterans.
We can assume that Anet did a copy and paset job on the scripts here. Same bug, different event.
But if you do you distribute nicely you will get more loot as you will be on more events with more champs naturally as you do more events because the HP do not scale that much. The numbe of champs seems still to be capped per event.
So bigger zerg does not mean more champs. The champs just get more HP and it takes longer to kill them with the same loot. The event is time scaled on HP as it looks.
Just a smaller zerg is enough to get an event to champ level. Kill, loot, move on.
So the farmers are just hurting themselves by getting less loot and denying other a lot of champ bags because they run with farm commanders not understanding the scaling mechanics involved here and think more people will produce more champs over the whole invasion on a per event. This is not correct.
When I played the first day without the farmers we had champs everywhere because of distribution (we ran with about 5+ experienced WvW commanders) and came out with about 50-60% more champ bags (unless Anet silently nerfed minion events).
But hey the “pro farmers” always know it better, right? That’s probably why they still need to farm so much. xD
So, still waiting for the 13th map to finnaly show up (should be Timberline Falls) so I am done with the farmzerg-fest.
But in general the pure PvE commanders are the worst. Event fails, does not properly scale to champ level and people are dying because wrong mobs are attacked first. Even the farmers can do better than these guys.
