Using aether against aether is a bit risky... might catch them off-guard, though. As for light against fire... no armagios? Those, at least, have some resistance to fire's CC... but I suppose we don't have any other options, aside from mono (and it's not like we can make that viable a mono either, if we don't have any more armagios or g-shields- though the shields wouldn't help against fire either)
