I really don't see why not just like I don't see why melee are not able to make use of Quelling Strikes either or have a melee equivalent. Yeah Ninja specifically can transfer eminity to another target but if you overgear any Tank as any other class you are forced to hold back or else risk a potential death/angry tank.

There are at max 8 players per party but almost double the jobs yet some of the choices in regards to TP sustainability or eminity reduction are not standard amongst classes as a design choice. Having Bard is Machinist supply TP is all well and good but at least for Bard it is a direct decrease in damage in a state where, because they are technically a DPS, to meet a damage check. And yes you can time when you supply TP, etc.

It would be nice to live in a system where you would take or want X, Y or Z and not need X and Y because of a long fight but also Z because it is a long fight and we could use utility damage speed it up per TP cost. But also need W (a Tank) to generate a lot of threat because of lack of standardization which means less damage and a longer fight due to not necessarily using high potency combos.

I know, I know you can get around all of this and the game is doable without these tools on all classes but this is just something that has erk'd me since I started playing. So long story short yes I agree.
