DPS jobs lacking utility?

[Taranok]

There is no situation after Lv45 (when they switch to INT-only gear) where casting it will change the number of times the enemy has to hit someone to kill them, so no, they don't have a heal.

Now now, there is a situation where it will add + 1. Once in a blue moon, maybe.

Honestly I really don't understand why Summoner has Physick, except to give them a wombo combo in Bozja due to qualifying for a certain deep essence.
