D2R changes ported to LoD 

I ported most of the balance changes from D2R in the mod. Pretty much all I could do without hardcoding. Here is a list of the most impactful changes:

Skill balance and synergy changes (95% of them anyways)
D2R runewords (all except Mosaic; Metamorphosis is bugged as it gives you both buffs regardless of your state)
Nihla temple vipers fixed (their poison spray applied their main hand damage every frame)
Mercenary changes except for the equipment changes (so no dual-wielding and equivalent class)
Upgradable set items (same recipe as in D2R)
Andariel quest bug fixed (always drops from quest TC now)

Here is a rather incomplete list of stuff that is not changed due to mod limitations:

Mosaic
Local delay
Next hit delay
Fist of Heavens and Holy Bolt changes
Whirlwind and Druid form attack speed calculations
Assassin traps benefitting from -%res (I told them to do that, but haven't tested it)
Mana burn fix
Sunders
Merc equips (horrible hardcoded mess)
All of the above require hardcoding, this mod is soft-code only.
