They could make a magic tank that works well – Perhaps Geomancer/Elementalist which uses elemental spells as magical armour and perhaps elemental weapon enhancements like en-spells.
Some of the abilities could work similar to Ninja shadows in XI so you would have several spells with varying cool downs that put up a number of magical shadows that absorb physical damage. This could be combined with Stoneskin type elemental spells which would absorb damage in different ways (Water Wall, Lightning Shield, Wind Guard – Just ideas) which could be weaved in between the shadow spells.
