I think it would be beneficial to slow down the affinity XP gained from expedition sites. I think a big problem is the Free Level bonus from progenitor ruins/devices which is not only too powerful at higher affinity levels with their higher costs, but also because it's too convenient since you get to choose exactly what you want to level up. The Free Level bonus should be removed from all expedition sites and replaced with random affinity rewards like the existing ones from Alien Skeletons and Kraken Nests. All other rewards are random afterall. That would help things, but to also make it more fun and fit the hybrid theme of Rising Tide, there should also be different combinations. This would also help to slow down hard beelining through affinity levels. All total to 12 XP points. (For reference, the existing one in the game rewards 12 to 14 XP points.) 1) 12 xp in one random affinity. 2) 8 + 4 xp in two random affinities. 3) 6 + 6 xp in two random affinities. 4) 4 xp in all three random affinities. Spoiler : Alien Skeletons and Kraken Nests could have a chance to reward 2, 3, or 4. Progenitor Ruins, being more advanced and unable to continuously spawn on the map like Skeletons and such, could reward 1, 2, or 3. Progenitor Devices, since they only rewarded random affinity xp or a free level in the existing game, would be able to reward all four combinations. To test out this idea, I've created a mod which does all of this: http://steamcommunity.com/sharedfiles/filedetails/?id=561829843 Also, it would be nice to see PlotBonusSystem.lua receive the same treatment of the other "system" Lua files and check mods first for scripts before the default game paths.
