Well, I don't think it was just because of people not realizing how good the potions were, or how not good they were at any point. I certanly didn't know untill something (cant remember exactly what) made me have to look past The Hack and see what other features the game has if any. I was quite happy with the Tribute-XP-Dodge-Hack-Convert combo. So much so that I could just dismiss CYDSTEPP as a missclick-death-inducing-shmuck-bait strat, and not feel too bad about it.
Was pretty surprised when I figured out TT handed out something very much like cydstepp on top of what I was allready kicking-a***s with. ^^
So it was more that TT didn't look like a good choice compared to other god's and probably wasn't fiddled with by too many people, since GG and whoever was big ATM got more attention. Spotting the potions just sort of brought attentiont to how silly he was, which was funny to see at the time because not 2 weeks before a couple of such "breakthroughts" people were complaining about him being underpowered.
And then he was in all sorts of VICIOUS runs, and people weren't even abusing him to the max ^^
EDIT: Sorry for all this nostalgia, but I just remembered what exactly happened. I either discovered the potions as a cheap solution to Thomity and Bleaty in Naga City (never transmuted a throphy at that) OR as a cheap solution for a random dreaded old Bleaty as a second boss Tinker gold farming runs (pre PQI?).
At some point the devs put a righteous wrench in the "everything is doable with TT monks" routine by nerfing... everything involved, pretty much

(some of it was purpusefully overbuffed previously, though). And the now present 2 -res floors in old Gaan'Telet were giving me trouble just before I discovered the potions. Then I did it a bunch of times with a TT Orc Paladin. With no other altars and about 10% of anything unlocked. And the old AA floor. And the old mana burn boss. And he gave no glyph, and GETINDARE only gave first strike. Dem potions, ahhh

Good thing they moved TT further south, that guy used to be more of a gamebreaker than Taurog -.-' I remember that I only unlocked GG by accident in the "2 gods whole game run". GG was even stronger back then, but I had no clue and was playing for ages -.-'
