what?

Mana Feed now restores more mana (four times as much) when the warlock is using a Felguard or Felhunter.

does this mean we will NEVER tap? like ever thats 16% of our total mana when our pet crits, this isnt a dmg buff really but it might be pretty nice to never tap again, still hope for more dmg buffs please blizzard like lower cast time on SB maybe?

That just makes them equivalent to the Imp/Succubus when it comes to mana generation. It's when your pet crits with its basic attack, which isn't its auto-attack. The basic attacks are:

Imp: Firebolt
Voidwalker: Torment
Succubus: Lash of Pain
Felhunter: Shadow Bite
Felguard: Legion Strike

Make sure Hand of Guldan is up 100% and we should be golden.
