Hmm I never run with any other mdps, all partys have only pdps so use other mdps class to compare would be only theoretical and not in same conditions for me. M/ch is better than d/wl if thats ok for you 
- M/K: Does not have good aoe anymore (burst atleast, b2 mobs and lake which is my whole post). Last patch got huge nerf on it so can't compare anymore.
This being said, I can only compare with other pdps I see in partys which are the list I said above. Now you are saying I can't compare my non-meta mage with any of the pdps because most of them are strong/op/broken? Well,I don't see anyone asking for nerfs here if they are that strong.
M/ch only purpose is aoe, it should have the strongest aoe in all mages and also should have one of the strongest in all pdps due to it being useless in balton, astaroth and any single dmg situation. So sorry but no, pdps having better aoe than this class (supports or not supports) when all the list I gave have incredibly good single burst in balton/astaroth doesn't seem fair to me. I guess people won't have the usual excuse of "this is a support class, dmg is enough".
But thats my opinion tho.
