Pros and Cons of each Healer Role

[Violette]

Short: Yes, with a but.
Long Answer: No, with an If.

In 4-Man content an extension gives you double the normal effect on a card, while an expansion gives you half the effect on 4 people.. or double the effect if you will. However since not all 4 party members are equally good in terms of output you get the most value from an extension on the party member most able to make use of it.

Well thank you mr obvious, however you must remember 2 key points:
1. 4 man content is garbage easy and should not be balanced around.

2. If you're in such an extreme set it up likely that DPS is very unimportant, rendering methods of increasing dps moot.

So I think the answer you were looking for was "yes." Because if you're trying to maximise dps, you would have thrown out the first spear on a dps so their cool downs would be back faster.
