Summoner Primal Limitations

[Sangiin]

For reference both Physick and Eye for an Eye work, and you can cross Stoneskin as well.

However, the main idea is so the player does not carelessly use the pet. Making it invincible would make it the "best" tank in the game assuming aggro is held, beyond the free, no downtime damage/healing. Tools to keep the pet alive are wasteful when proper placement and movement can do the same. Besides which unless they were free, simply re-summoning would be more cost effective in the long-run anyhow.

I personally think that with the abilities listed above, your egi should not die especially if you are communicating with the tank so your egi isn't (Assuming you aren't running Titan) If the fight feels like it needs a switch i personally will use a swift cast CD to change it up as you can make up the mp fairly quick by using energy drain instead of fester sometimes. Especially since aetherflow is only 60 seconds as well.
