Because every part of EVE is important
Disagree. Vehemently. The potential for profit should not be curtailed. It is the same for the people complaining about people in low sec making profit. Everything in hisec exists in lowsec/nullsec in bigger and better ways. You can't punish people for making isk in hisec.
The real issue here is the isk being made by incursion farmers. For the first time there's an income stream in hisec that approaches the reward levels of those of nullsec. It's not ‘zero risk', as I keep hearing, but I will agree that if you know what you're doing and you're flying with a competent fleet, the risk factor becomes a lot lower. There are still ways to disrupt incursion fleets though and we do sometimes see Concord in sites. As far as the farming goes - why not? It's acceptable to spend all week farming Worlds Collide and Angel Extravaganza - why not sansha spawns? I do think that the various sites could be better balanced however. At the moment almost everyone is running Vanguards because they give the highest isk per hour ratio. It would make more sense if Assault sites were buffed so that they could hit the same ratio if done properly; thus making site choice purely a matter for fleet size. HQ sites are kinda pointless just now because no-one does them. I'd also like to see the Kundalini Manifest only spawning after a set time period - say 3 days - and only remaining for a limited time - if a fleet isn't formed to kill it within, say, 6 hours, then none of the LP pool gets paid out - thus encouraging all the little separate fleets to join up and get the job done but also DIScouraging disgruntled pvpers like Kissada from spoiling sport for the incursion runners.
