I've literally only read it once.
If I start reading it, I'll feel compulsed to scroll through everything every day - and reply to everything. Soooo no. I refuse.Indeed.
However, in content that doesn't last 8 turns - you didn't need that Atk to begin with. Is it ideal to take Vine out for stuff like Advent Ragnaroks? Sure. Do you need to? No.
In content which takes longer than 8 turns? 16% extra damage. Assuming that your Hime are around 40k Atk as they usually are - that's the same same as 6400 Atk. So effectively, you gain ~5000 Atk for content that matters - a net gain of about 13%. No small feat considering a P2W Eidolon is considered OP as fuck, for about ~25% gain.
And the stronger you get, the more reaching Def cap helps you.
Of course, if you have ways to reach -50% Def WITHOUT Vine, then great. Dropping Vine just means more base Atk for you. However, we're still extremely short on those. Namely:
Water - Cthulhu
Light - SSR Tsukuyomi
Fire - Mars
Wind - Hraes
Dark - Thanatos (plus partially SSR Amon)
Thunder - Charles Blast (HA HA WE WISH)
Three of these have been available from Miracle Tickets so far. One of these never will be available to most people. For now, only Thunder is capable of -50% for absolutely everyone (nobody is going to run Charles Blast outside of Thunder, right?)... ... or would be, if Nutaku were to fix their shit.
Anyway. The point is, Vine goes to every team unless you _specifically_ have one of the above. As time passes on, the list above will expand more and more. As such, Vine's relevance drops more and more. Particularly Hercules' Relic weapons will probably drop Vine entirely. But that's then, and now is now.
Oh, and I guess if you insist, you can drop Vine from Ultimate Wind Disaster farm team, since it's rather unlikely to help.This I believe.
