Quite simply, I can't see how these sites are going to be remotely worth it if 5 Marauders can only earn 24 Million/Hour including LP each.
They need to go back to the drawing board on scout sites, and make them different somehow. Make them about small ships, say.... Cruiser Max. And make them reasonably Isk/Hr competitive.
VG's I'd leave as is, since Vanguards often did have heavy elite troops in historical terms.
Make Assaults BC max, and redesign all the sites to be about mobile BC fleets (Obviously HAC's, T3's & Logi's would still be involved) and ship speed combined with good tank. Fast strike in and back out somehow.
Then you have most ship sizes involved in incursions, Frigates/Destroyers might still get left behind a little but Cruisers are highly accessible to a new player.

right, a couple hundred guys earning 100mil/h broke the economy, while there are people earning hundred of BILLIONS out there.
first of all, incursions are limited, there just so many sites which can be run by just so many people.

first: were did you read the "per hour"?
second: you still didnt explain how something so limited in scope and number of involved players can break the economy.
there's a finite number of incursions that can be running at the same time, each of those can have a finite number of sites at the same time and even if you drag it on by not shooting moms its duration is finite.
each of those sites have a fixed number of maximum ships that can enter and a fixed payout - even when one of these sites get contended only the winning fleet gets the payout.
no way in heck this can even jiggle eve economy, lets not talk about "break" it.

the same would happen with pirate fregates and such.
anything that can help low isk - low sp players do something would help more high isk - high sp ones.
they solved this problem in high sec ded 3-4 by excluding t3 ships, the only solution that can keep eve players from using ultra costly/blingy ships to min-max wathever ccp throw at them is to stop those ships at the door.
but I dont think its a good solution, you just have to accept that older players will min-max any pve content at the cost of newbies.

read better the same post and thell me where's the "billions/hour" comment.
if you assume something, you know what they say about people who assume things?

in an economy like eve, where people losing trilions in ships like the last bruhuaua in null make only a small blink in trit sales, it is completely meaningless.
just bother to look at available data instead of just assuming (again...).


and would you care to post your statistical data about how these changes would impact eve echonomy in the short, mid and long range?
where's your data coming from?
you are just jumping the "there are a few guys in hisec making money, lets chase them out of MY game!" bandwagon, its making you looking jelous as hek, but feel free if you want.

again with the "if we nerf high sec enough its players will come here" bull
high sec players dont like playing in null of they would be already there.
if you remove all content from high sec, you just remove any interest for those players to play eve.
and if you lose enough players your nullbears wont have enough money to keep paying ccp servers and people.
would you like a 150$ montly subscription?

its not a question of money, if you place anything in null only people blue with the two coalitions will be able to run them.
and if you are blue you can run them in wathever ship you want, you just need to look at intel and warp to pos when needed.
if you place them in low only a few people that can hold that system completely locked for the period or friendly with every local denizens will be able to run them, exactly as it happens with level 5 missions.
for everybody else would be suicide.
so basically you arent lowering the isk/sp factor, you are just removing them from most player's reach.
