EQ Questions

[Rolien]

Plain title to say the least but states the obvious.

It's been a hell of a long time since actually playing live when Velious was the most recent expansion since then I have forgotten quiet a few of the changes that were amazing at least to me. Things that didn't break anything but just made life easier.

So questions are:
Currently Some Classes and Races suffer an exp penalty around when was this removed?

Also currently arrows are only stack up to 20 when was it changed to where arrows stacked to 100?

When were Halflings allowed to start up as Rangers and Paladins? (I'm fairly certain this was during LDON but not 100%)

Currently if a pet does the majority of the damage the caster only gets 25% of the experience when was it changed to if the caster does no damage to the mob they gain no exp for the mob?

I have also read that mobs are still at the zone in of Hate when was this changed to where the zone in is safe?

Just curious if anyone is able to answer the questions about what expansion these things were changed in. I remember dealing with the issues but just can't remember when they were changed.
