Much of this is speculative as a bulk of the work was done after beta shutdown, or involved talents that need more data than what a few leveling logs can provide. There's a fair number of core changes to support effect parsing for things we don't see or worry about in retail. Commits not tagged for Druid are worth getting more eyes on imo.

Some big things:

• Parsing for hit and spell hit
• Parsing for mana regen multipliers (innervate)
• spell_t now has an override for execute_time_pct_multiplier to properly account for spell haste.
• Related to above, swapped the subtype enums for cast speed and spell haste, given the Forever spell data has a bunch of spell haste effects with subtype 65. This is different from retail, which uses 355. Curse of Tongues is a good example showing the swap from retail to classic.
