So what exactly happen in v1.0?

Coz most, if not all MMORPG that I played seems to always have a pattern, or I'm misunderstood your term "scripted".

It's always a "time-triggered" or "HP triggered" attack, or a position dependent attack, but still all of it are scripted.

So which is which?

I'm not sure if we can discuss other games here, if yes, please do tell me so I can elaborate my example above.
