The reason for this request is the following...
1) It makes perfect since that earth magic with is major protection abilities should give you this capabitiy somewhere. Plus the connection with the earth (what your standing on) would be a good basis point to help keep your footing somehow as another view point.
2) As a spell caster, it really, really, really, really sucks when I get knockdowned. I loose not only the spell I am casting, but also all the energy I was using to cast it (which can be pretty major when some spells cost 25 energy). Also, resistance to interruption enchantments such as mesmer skills still don't stop knockdown attacks from interrupting you. Personally there should be the ability to resist it in one of the caster type skill list and Earth magic makes the most sense to place it there in my opinion.
