The only map pack type mods I currently use are:
- World Expansion Project: Advent
- Dragon's Wilderness PCPs
These packs only include Parcels and PCPs (plot cover parcels), so they have little to no effect on timers. Quite a few of the other map packs include Map Plots, so I've been avoiding using those in LW2.
Doctor_Mandarbs_Map-Pack also only includes PCPs and Parcels, but it is still very new and may include issues that cause problems. Not the safest mod to use in an Ironman game or without console commands.
MGee's Maps seems to only include PCPs and Parcels, but some of those Parcels are quite huge and different (a warehouse, a highway full of vehicles, etc). It might be OK?
Even More PCPs seems cool, but has a bug where the game freezes on some City Center type maps, which precludes fully half the mod.
Most of the other map packs include some number of Map Plots, but I'm not sure which ones are balanced properly for LW2 Legendary play.
