Using Stoneskin as a paladin, should you have it?

[Shenon]

It can be a great boon proving you know when to use it. Here are some scenarios I utilize Stoneskin.

-When Titan/Ifrit Jumps
-When Garuda is traveling to you after warping
-Casting on yourself and the other tank when switching during Turn 2 of Coil
-Off Tank throwing it up on everyone after the wyverns in Turn 5 of Coil, making the first Fireball more sustainable.
-MT/OT throwing it up right before Twintania uses Death Sentence.

Pretty much those, and
- If you have a SCH in the Group ,and doesn´t have that Skill (happens often in DF Groups...),for example in AK. Casting that on the Wall on everyone or before big Pulls can help a little.
