Okay.... As because of balance reasons mining factions cannot land at each other's bases (the only exemption is for Daumann and BMM due to RP written by the devs, and only for 2 bases), I found there's a loophole in that system.
IMG and DSE, 2 mining factions with common bonuses to ore, can land at each other's bases. Someone can say "but DSE doesn't do that much mining." Well, it does. DSE mined out entire Colorado, that's why they have the best bonus to silver in game. Again, you can say "but IMG outposts were originally built by DSE, Holman, FP4 and Freistadt". Yes they were, to construct lanes in their systems. DSE builds also lane for Daumann in Omega-11, yet they are rephacked as non-dockable to our bases, because of balance reasons, as former DHC asked for it.
DSE and IMG, mining factions with common bonuses to Silver, Copper and Platinum ores, should be rephacked as non-dockable to each other.

This is one big joke, that IMG has same bonuses to Cobalt, Copper, Silver, Gold and Beryllium ores like house factions. It shouldn't be more than x2.0 bonus, to just accent it's slightly better than generic miner ID.
