From ME:
 * 1) Agree about the heating mechanics.  Conrad Verner is right about that being a step back.
 * 2) The lift power
 * 3) Ability to use life and throw on even huge enemies.

From ME2:
 * 1) Agree about heavy weapons.  I want my Collector Particle Beam back!
 * 2) The charge power
 * 3) The reave power (the ME2 version)
 * 4) The shockwave power (the ME2 version)
 * 5) Going behind low cover without having to hit the kneel button
 * 6) Ability to order squadmates separately
 * 7) Elimination of the inventory system.  I absolutely hate inventory management.
 * 8) SMGs
 * 9) Tactical cloak ability
 * 10) Layering of enemy protection.  Just like the way it looks.

From ME3:
 * 1) Combat rolls
 * 2) Heavy melees
 * 3) Going over low cover without having to duck behind it first
 * 4) Cluster grenades
 * 5) Life grenades
 * 6) More opportunities for biotic and tech explosions
