Since we now have access to the #mystats command, we can finally put to rest all the statistic cap arguments.
Strength - 650
Dexterity - 650
Stamina - 590
Agility - 550
Wisdom - 550
Intelligence - 550
Charisma - 550
All Resistances - 650
Haste - 100% from Worn and Version 1 Spell Effects Combined.
What this means is you only need around a 30% Worn Haste item to cap your haste with the buffer.
Version 3 Haste from Primal Guard Click will take you to 105%.
Bard Haste v3 will take you up to 135% (Hard Cap)
Easier to Show with Screenshots on the Haste:
55% Worn Haste + Hastening of Salik:
100% Haste

55% Worn Haste + Hastening of Salik + Primal Guard:

105% Haste
55% Worn Haste + Hastening of Salik + 70 Bard Song:

135% Haste
+Attack from Items Cap: +250
+Mana Regen From Items AND Spells : 50
AA increases allow you to go past 50 but not enchanter mana regen spells or click items.
What this all boils down to is:
1) Raiding for Gear on THF is more about the Spell Focus Effect, Melee Focus Effect, then the actual statistics on the item. Though HP and MP and AC are still important.
2) You will cap your haste out around SSRA, along with your Worn Attack.
3) You will cap your mana regen by farming Sol B mobs.
4) Statistic Cap increase AA's actually cap your stats at the listed ones and not your displayed 440 in the UI.
5) All of the above cause your HP, MP, AC, Attack, Resists, and Stats to be wrong in your user interface display, you have to use #mystats to get an accurate read.
Thanks to Kilmer and his maxed AAexp for helping to test the caps. Thanks to Kermit for providing the Bard to test Haste cap with.
