Ok, I'll proofread and finish up the "guide" tommorow, to tired to think now. Whole bunch of stuff came togather though, and a whole lot of stuff makes sense now. I have a whole lot more understanding for many situations where my reacion to someone's complaint was "whait, what?", least of which were the LEMISI complaints.
However Nandrews edit/comment about there being too much blackspace is probably spot on. You get blackspace in every dungeon in coupious amounts and as long as there are easy to use cheap preps that let you level ramp (slayer wand, STR potion and so forth), and low hanging stuff that lets players get more out of their blackspace than they are supposed to (and what that is needs figuring out) regen fighting as the end game focus will be optimal in every case where it's not directly countered or taken into account. I think I can sort of prov it by math, and also that it doesn't really matter.
3 things off the top of my head - the way -res guys compeltely shut down some classes and not others, the way poison against non undead bosses (not counting mana burn ones) can quite thrutfully be interpreted as a hack, the way regen fighting was always the only thing that could beat Gaan'Telet (even now with the Bloodmage). 4 - the way I used to measure the "sucess" of my varios old Gaan'Telet runs by how many bloodswells did it take, feeling more chipper every time I had less need to resort to spiking like that.
It's not unfixable though. Bosses who revealed random parts of the map when you hit them, for no regenerative effect to either you or them, would be hilarious. Monsters which did that, too. Plants like that would add an inconspicious, spiker friendly obstacle to the plant roster... Reducing the number of things that inadvertedly let geared up wannabe regen fighters get away with using all theit perk without actual blackspace (main reason why the current Drac feels realy wrong right now, his "free hit string" actually synergisez with stackign damage res/red, and requires far less effort than either TT's or Taurog's).
