What is terrible about highsec incursion mechanics? Can you elaborate?
I think if you bothered to look at the data available to us from CCP you will find that incursion payouts are actually in a good place, compared to say… bounty payouts.
I know you’re probably to lazy to educate yourself, so I Google’d it for you. Here’s the monthly economic report from September 2017: https://community.eveonline.com/news/dev-blogs/monthly-economic-report-september-2017
So the biggest issues I see is that lowsec has a very small slice of the incursion payout pie. That likely has way more to do with the actual state of lowsec rather than an inherent issue with incursions.
Highsec incursions are really fine in my opinion.
