This is the kind of thing I'm afraid of. Especially the MDS relationship. I almost never play online, like many people here, and I don't activate the MDS. As I understand it, it conflicts with all kinds of things.
The friction mod might be great for mapmakers, but if people have a lot of problems with it, then it will be hard to use the map for missions and campaigns. Then a nice map might just end up as eyecandy. AFAIK, don't blank plates work for everyone?
Ahhh, but the Friction Mod is not the same as the MDS Mod (Moving Dogfight Server). I never ever play on-line either (the few times I tried I got shot down while trying to take off ...). I too have had conflicts when I tried out the MDS mod without really knowing what it was.
There is a stand-alone version of the Friction Mod and there is a MDS compatible version of the friction mod. And from the posts I've read on the Friction mod, there doesn't seem to be any conflict with maps that have the mod and members who don't have the mod installed.
So not to worry about maps that have this mod. In fact, it isn't really the map that has the mod. It's the player who installs it and then the player's game can read some extra info contained in a map load.ini file concerning areas where there is less friction on a particular terrain area so that it can act as an airfield.
There should be no conflict therefore with the Friction Mod.
Groundplates do work for everyone, but they do effect frame rates when airfields are large and intricate, with lots of invisible groundplates. And if you've ever tried placing invisible groundplates over an area and tried to do so properly, mull for a moment on the term 'invisible' ... they are literally invisible and once you place them there is no way of seeing where the little suckers are ... try correcting mistakes on something like that ...
And other groundplates, the concrete, sand, green grass plates and all, are really a bit outmoded and look dated, as if they don't belong in a game the caliber of Il-2. Airfields look ever so much better using integral airfield textures like those by Mixx or Compans ...
So not to worry. The Friction mod will add an extra dimension of challenge when landing and will allow such little extras as making emergency landing fields to be easily placed and made.
Don't forget that the Friction Mod is not the same as the MDS mod and comes in a stand-alone version and is easy to install as well.
