Let’s go back to the good old days.

starting for: Galthran, Shakti (only as starting heroes) is banned

has anyone ever tried to build even an Eye on 200% for Dungeon? ;) where do you get all the resources, even if it's just a penny here and there? The Miner has nothing better to do than to defend them, and the others are almost zeroes even with his Troglodytes
if they do build, as a rule in half the cases it's on day 6 or 7 (Citadel is already up by then, and maybe you'll manage to squeeze in Medusae))) and it's also a good idea to get a Marketplace well in advance :)
of course, Dungeon with the Miner is undoubtedly the most penetrating on Impossible, but it is also one of the most unstable -- unlike the solid Rampart, Castle, and Fortress (although the latter also has trouble with early Flyer construction on 200%)
if you don't get the right Conflux and normal digs -- you're outpaced starting from week 2

in other words, nobody will just pick Dungeon... but as it is, on 200% on XL it averaged at the level of Rampart, well, top players quite willingly played Castle-red vs Dungeon pairs among themselves))

Added after 4 minutes

in group "C" there is 1 player missing, in case there are no volunteers (specified in the rules) then we'll play as is.

on XL, together with the blue color, I'm ready to give Dungeon with the Miner to anyone ;)
