I have now moved away from girls that are not team wide buffs as much as possible for the sheer unreliability of them on a team scale.

Same here. Gladly, those buffs that only affect 2 or 3 squad members become pretty uncommon for 5* girls obtained from Gacha (while it is pretty common for event girls) and almost non-existant for Rainbow girls. Even if the buff for 2-3 squad members tends to be higher than a similar buff for all members, I rather have Alpinia with a guaranteed +20 ATK buff than a flaky 30% ATK buff.
