That makes no sense because this game is designed to be highly rotation-and-script-based. The 3 "-of the Green" Spells are designed so that they can be rotated and all three can be of some use.
And I do like BRD's SB redesign. It flows well and its songs are a far greater part of its design, as oppose to 1 song that needs to always be playing (Foe's) and the two resources refreshes (Mage's and Army's).
Focus and Tranquility (the 2 "-of the Green" Abilities) can't be used at the same time and Bravery, Faith, and Poison (the 3 "-of the Green" Spells) can't be used at the same time. You can have one Ability and one Spell up though. The abilities are like Stances, one to increase your DPS range, one to increase your heals.
I would imagine that the MP cost for Tanglevine would increase with the trait. I usually don't post MP costs because they increase as you level.
Both Drain and Syphon are both Green Magick spells in XII's Zodiac edition.
Lore-wise, it's more like you are temporarily connecting those affected with Syphon or Whisper with the Green and the Green is rewarding them for fighting the enemy by healing them. You're not actually draining the enemies' life force, you're just getting a reward based on the damage you do to them.
