I think we should go back to chemical powered weapons like our modern weapons. When you sit down and do the math, our modern weapons do far more damage than the metal shaving block weapons in the MEU. Even the M-920 Cain is a piece of crap. Face the facts. the old Soviet army circa 1970 would have had more success against the reapers than the Systems Alliance in defending Earth. A bullet is a bullet.
A localized EMP would take out MEU weapons and tech armor. You'd be left with knives.
except ME weapons are more resource efficient, at the cost of slightly less stopping power.
That's why bringing back Ammo was so retarded, because it completely negated the "resource efficient" aspect.
Also yes ME1-3 weapons suck because they are just slower versions of conventional weapons. Its ME1 weapons that were awe inspiring, due to the adjustable design and functioning more like rail guns (Seriously, sniper rifle with Large Caliber Rounds and High Explosive Rounds? It becomes a straight up rail gun. BOOOOM!)
