There are alot of things in this game that can be contributed by various means from various classes. As an example, two staff guardians can contribute 24 stacks of might with a staff and a warrior can contibute the might to get to max 25 stacks. Alternatively eles could lay down firefields and another class such as a thief can blast it with their short bow. But what exists that cannot be contributed to a party by other means? I asked this as I was thinking about the warriors banner of discipline and banner of strength. Yes you could argue that these two abilities might be able to be compensated for by other means but I don’t see it the same way as say the example above of 25 might stacks from other sources. But what other buffs like this in the game are there that can only be contributed by one means and cannot be directly compensated for?
Yes this question is from the so-called “elitist” viewpoint of maximising DPS for speed runs
