- We had Muffin.
- Dread Spikes didn't cap on max HP, it was effectively up forever.
- All TOAU and some WOTG spells were in; biggest one I can think of was Abs-ACC (yum).
- Hasso didn't come with a recast penalty.
- Last Resort lasted the correct 3 mins (still salty about the nerf).
- Desperate Blows was considered a class ability as well as a merit.
- Weapons with procs, didn't. It was very exciting when DSP finally started coding them.
- Footwork was in and was affected by +Kick Attacks DMG items (Oddin and I could probably have duo'd a lot of the later CoP fights because we both had Seihanshis).
- Bunch of wonky WS behavior, some of it unintentional on Nas's part and some of it imported from bad/unsourced coding on DSP.
- There was one, massive endgame LS run by Muffin, it was called BloodMoney and your invite was not guaranteed (hah).
- Formless Strikes worked on WS (this was hecking fantastic, I wish it had never been fixed).
- This wasn't "from the beginning" but there used to be a bug that caused an effect on you to become permanent duration after zoning; everything was fair game (this is the Flee hacking referred to above). I ran around with Last Resort and Blood Weapon permanently up for a couple hours before I felt awful about it and stopped ;p
- Adaman turtles had no TP moves and dropped Ores like candy.
And much more. Exelyon, Cityhunter could probably go on for days

I'm going to go against the general consensus here and say there was a lot that I really loved about early Nasomi. I miss some of it a lot.
