Also : here is screenshot:
i dont know what you dont like in gates but working properly - here is result. Dont tell me that THAT GNOSTLING stack sucks.
All str 5 units with crazy speed of xp gain.
thades are chosen ones, mostly teleport scouts, hasters, charmers.
Faollowers comabt 3-5 stoneskin (earth 2) and malestrom (air 2) casters.
This is immortal level all options enabled except tech trading game. this stack going to kill , and alot.
Now update: check that, as you see it very few = 12 (!!!) turns later .

Compare 2 pictures. Same 5 str gnoslings stack but with combat 4-5.
IMO we should to be carefull and not to make Kahdi too overpowered. They are already are very very potent.
Btw, ~60 of my 219 tech i getting from city garnisoning follower casting insporation. 4 beakers X 30% boni from Repr and +20 from Scholarship = 6 X 10 cities = 60 beakers, more than 1/4 of my beakers output. This is powerfull too. And very refreshing tactic btw .
I ensure you that Kahdi already pretty ok, and need not much of tweaking. As using alot of sage buildings and scholarship soon , and great lib, most science come from sages/buildings/inspiration . as you sewe on that screenshot - i have my sci
at 0% and have still 219 beakers per turn. that mean gambling houses add +10 happiness in city they being built.
They rock without religion and heroes. The stuff they posess is already powerfull and enough to kill stuff around

. I cant imagine amounts of units in this stack once i resereach Strenght of will and build Rites of Oghma. 30 strenght ~8 combat 5 promoted units? thats already too much and such army ( str 8 combat 4 gnostlings) can wipe alot on its way.
