Ewer and Spire are often (not always, but often) useless to cast. There are many situations where you will draw one of them and have no one who will benefit from TP/MP refresh. As a rule of thumb, if there is no one who is at risk of running out of resources, you gain nothing by buffing their resource generation.

On the bright side, Spire can be helpful for physical DPS using AoE skills on large pulls or for WARs having to spam Overpower, and so on.

Bole is almost always useless to cast since you rarely draw it when you would actually see some benefit to applying it. If using Bole doesn't significantly reduce your healing requirement or allow the target to survive something that they otherwise wouldn't, it was a waste.
