C4s are pretty high up there solo ISK/hour wise, second only to C5s. Doubling it is extremely over the top and no you should not be able to jump caps into C4s.
C2s are FAR more important to address.
In any case, it's being worked on.

How did you arrive at this conclusion? Have you tried to run a corp (5-10members) in a C4 with all corp members revenue coming from anoms alone?
If one person were to solo all the sites then what exactly is left for the remaining corp members? I encourage you to approach this from a different standpoint. Don't just run a handful of sites then compare isk/hr. It just doesn't work that way. That approach would be sensible if wh sites were infinite but we all know they aren't.

Welp, first time the forum has eaten my post.

My bad about earlier. I know you are working hard and I was just trying to explain things from a different point of view. Back then, I was giving an example of a possible scenario. I never clearly stated that one guy in my corp was running all the sites. As I said earlier, I don't think balancing combat anoms by isk/hr is the optimal way to go about it or by comparing isk/hr of solo C4 running to that of 5 or so guys running C5s.

My main point is that the difference in isk making potential between a C4 to a C5 is too huge given that they are just a single class apart and even now more of a concern given the increased exposure of C4s.
For example, running 8 combat sites in a C4 yields around ~750mil to be shared by 2-3 pilots and it would take around a week or longer for another 8 sites to spawn. 8 combat sites in a C5, on the other hand, with full escalations yields around 5-6bil on average multipled by 4 so about 20-25bil a week to be shared by anywhere from 5 to 15 pilots or possibly more. Either way, each person is making X5 or way more than your average C4 resident.

It's easy to tell me to pack my things and move to a hole with a more lucrative static but it doesn't fix this huge discrepancy in isk making potential that's just not meant to exist and is possibly one of the reasons why C4s aren't seeing that much activity.

Hey corbexx how is that wormhole class income list coming along?

P.S. Add a single carrier only escalation wave to c4's maybe?

Lot of ppl rat these sites with T3's I think, and mini-escalating with T3's would help close the production/destruction loop for these ships and raise demand for them. Virtuous circle stuff. Keep in mind this would more than likely increase supply of T3 salvage so it would be better to have T3 ships put at risk for this so more of them get blown up. Lore might benefit because "sleepers get pissed off seeing their own technology used against them", etc.

I really doubt that a lower class income buff is going to threaten the competitive advantages of higher class holes and cap escalations there. The latter is already the highest gross isk/hr in the game (says Fozzie). Narrowing it somewhat will still leave a reasonable gap.
