It's fine. Check if you see the same tendency in the Wilson B-factors -
it's entirely possible for a wild-type and mutant to differ that much in
overall B-factor (there could be many reasons for increased disorder).
At this resolution anisotropic B-factors for protein atoms are probably
ill-advised. If you have heavier atoms (e.g. metal ions), then it may
be OK to treat them anisotropically. Ultimately, the decision is made
based on what happens to electron density and/or R-values.
