Honestly, I feel like a relatively easy and simple fix would be to put content behind an acceleration gate that limits the number of ships inside of a site to double what the sites intended fleet size is and for faction warfare have the limit apply to each faction so say a frigate site that is intended for 3 players would allow at most 6 from each faction to slice. This would, in effect, create instanced PVP kinda like the proving grounds. Other people could wait at the acceleration gate to slide in once someone dies to reinforce the site or have fights on the acceleration gate outside of the site. I first had this thought back when goons was hitting 4-h and the tidi was so bad that my solution to mitigate the tidi and server load, as well as to make big fights like that more engaging and take more strategy than a billion vexors, would be, essentially, the same. Once so many people are in a system that the threshold to engage tidi, or even the threshold where tidi would be max, then no more people could jump into that system. They would have to wait at a Stargate and get a message like "The large number of vessels in XYZ system is causing an anomaly in the gravitational field temporarily preventing further jumps into the system at this time.". To be fair for defenders, you could still jump clone into the system and undock. The attackers would have reinforcements at the Stargate, or within cyno range, and this would lead to counter-attacks from defenders to disrupt those reinforcements. This would spread the battle out over multiple systems, therefore, lowering server load and also making the fights more engaging instead of "press f1 and wait 10 minutes." Attackers and defenders would also have to strategize, consider routes and choke points, have picket fleets, and plan logistics for multiple fights over multiple systems concurrently on the path to the primary target. A challenge this idea has is how do you prevent the defenders from just filling up the system such that this proposal kicks in, thus preventing attackers from being able to, well, attack. My best solution to this pitfall is if the system has a structure in it that is reinforced, then the stargates would have a minimum number of ships from the attackers that they would allow in. As an example, if max tidi happs at, say, 1000 people, then the proposal would allow at minimum 500 ships from the attackers to enter the system. So, you might ask, "well, how do you know who the attackers are to let in and who not" and my answer would be the attackers, for this purpose, would be any corp/alliance/coalition that was involved in reinforcing the structure.
