First chart is with crit immunity, second one is without.
You generally stack Greater Earth Elemental HLA for that nice damage resistance so I didn't include Fire Elemental form here. Greater Warewolf form is there because it's unique to Shapeshifter so I wanted to include that one. It's mostly for fun because you get Earth Elemental HLA as a Shapeshifter too so you generally use that one instead.
Gauntlets of Extraordinary Specialization is not something that a pure druid would typicaly use because other classes may have more use out of them. It's more likely you will use them on Fighter/Druid hybrid of some kind like it's shown here.
As a side note I used Moebius Toolkit 0.2 for this. Noticed that now I can hover over fields for additional information, STR tables etc. Saves a bunch of time. Great toolkit overall, good job @suy
