ayup, pretty much.
I didn't learn about that particular tactic until a month or two after launch. It's hilarious because the Sansha Incursions achieve whatever the fuck they're doing over the days their vat-grown fleets are killed, and when they're done the Capsuleers finally punt them out.
THIS ^^
This is, and has, since they began it, been my biggest issue with the current non-RP incursion running fleets.
Their response to IC requests that people assault the Revenant before their chosen time (started at 'mobilising' and has recently changed to 'withdrawing') is to either temporarily or permanently ban the character from the channel(s)
or to say that taking down the revenants as quickly as possible A) hurts people's isk making, and B) is against what CCP want for incursions... both points i feel have no place on the battlefield.
A) it's not about ISK. it's about war.
B) if CCP want to extend the incursions, let CCP fix it, don't force everyone to deal with incursions that last a week instead of a few hours.
fortunately the characters who have tried in the past to justify the farming IC have mostly fallen silent now, but the farming continues, and imho, it's going to continue until CCP either change the way incursions work, or end the story arc.
it's somewhat irritating how many people left the RP element of the
story arc as soon as it became more profitable to do things in an OOC manner. and how many non-RP'ers left low/null to come do highsec incursions because it was better isk than they were making ratting, and safer.
all that said, it was CCP's first attempt at making the incursion mechanic work, and it almost worked. for the first couple of months, while the primary place people were gathering to fight nation was an IC channel (SYNEPublic) ...
as ever though, things changed, OOC channels began to appear, and people left the RP aspect behind as the live events tailed off the first time.
fast forward to the second batch of live events, and the fleets that once numbered in the hundreds that used to form to expel actor led incursions, dwindled to 50-80 pilots, and that's on a good day.
**sigh**
let us hope that CCP learn from this farce. making the incursions as profitable as they are, made them exceedingly popular, and they are less risky now than nullsec ratting, as people have learned how they work, and countered the threat.
currently, my best suggestion, make them withdraw in 2-3 days instead of a week, or make the number of sites that spawn slowly drop off after the revenant appears. this will in the end mean that both sides of the coin (RP 'kill sansha' and OOC 'moar isk pls') get some degree of what they want.
TL:DR
imho, incursions are broken, and the sooner the sansha arc ends, the better for the game as a whole.
also: EvE is an MMORPG... why do so many people ignore those last 3 letters.
