RTF is a global modification that replaces all towns in the game.

What's the problem with high speed? Any archer/caster in the game has infinite speed. Moreover, some of them (archmages, high druids, forest archers, regular archers) also have decent damage.

Yeeeeeeees!!!!! And that's what I've been saying!!!!! They're stuck on a one-size-fits-all balance and are afraid to take a step to the left or right – besides, Tany and Faceless are large creatures, which means you can easily use them as cover, and by reducing the initiative of these units, the opponent will have time to either disable our fast squad or arrange their troops to provide cover – I've already tested it, and it's all playable (unfortunately, the test was with a dumb AI, not with real players, but I'll fix that ;) ).
