I don't care if it affects a familiar instead of say Lae'zel. The spell is so powerful it's already delivering value. (And with experience, my familiar is often not in the way.)

Meh... what if it affect characters that are not doing attack roll ?
You'll be fine to be driven to use specific spells because "bless is so powerfull" ?
Their system suck. Bless is a TARGET spell, not an AOE.
You look like the few guys saying that the chain system is so well designed...
