I'm not internet savvy enough or have the time to find a way to directly contact Jeff, but I've been through the bad side of the lymph node thing if you feel like talking to a strange adult on the internet.
I recommend you go back and play some combat in Mass Effect 3 and then revisit your opinion on the combat in ME:A. I've beaten all the games multiple times over the years and I've found they went to tightly designed interesting enemy encounters and mechanics to something akin to Oblivion with a double jump.
