Regarding TK3, that's spot on :) I once came across a Polish mapmaker's arena on GR (the description stated the map balance is perfect!). Played it out of curiosity - it was interesting, but it depends on how things fall: spells come from 2 Castle towers, where the structures generate randomly (issue number one, it's easy to end up without Slow/Haste/Shield/Dispel, etc.), artifacts generate randomly (there's only a choice of one of three artifact lines), skills aren't purchased from a full list like in TK3, but instead there's a University + Witch Hut - hope for random, and then finish off with a Pandora's Box for 40k experience, and that's considering heroes come without starting skills (resulting in you having to manually break the hero's skill tree from the get-go, which leads to warriors without Offense/Armor, getting schools of magic with no corresponding spells in the guild, etc.). It was fun when Tazar didn't get Armor for 15 levels, amusing when both Necropolis guilds gave Resurrection spells, but the funniest part - I told the guy it wouldn't hurt to reduce the randomness in the map, since it deals out very unevenly, and he replies that I don't know how to play (this was after I lost playing Necromancer), saying "come on, I'll show you how to play Necromancer"... Fine, he deals me a random Conflux, the guild has Prayer and the Hut gives Water Magic: the Necromancer got smashed to pieces, and he even got the Mage hero... He flat-out refused to fix the balance, it's "perfect" :)
