What are the list of things that were in classic but not in P99?

Charm pets do not return items when you kill em, on live I carried a charm kit (weapons, haste item, negative mr items) to give to a long term pet. Here you just lose everything.

A correlation, you could give mobs things on live without charm -I would seed low level areas with excess gear (rather then giving away). This did have some bad effects on live, some rogues would sneak up to raid mobs (that their guild couldn't kill) and give items to the mob (ie the sword that procs self dispel).

Creatures run to late, making a snarer obsolete in groups.

so in P99 or live, u can give items to mob, and when the mobs get killed the players looting the corpse will loot the items too?

I didnt know that. Something new lol.
