^ Approx 50/50 split as above would be my preference and expectation.
We know nothing of current.
Making it too "pew pew" woosh laser kapow like Mass Effect removes a lot of the impact. To paraphrase Zero Punctuation - I want my shotguns to sound and feel like god slamming his car-door. Weapons need weight and lasers just don't do it.
In fact in the current game many weapons don't have the "impact" other games have, cannons are somewhat muffled etc. Frags sound pretty awesome tbh if a bit metallic.
For examples of bad games see TF2, Mass Effect etc, for good examples try the Barrett 50Cal on a COD game or Serious Sam's shotgun, or painkiller. Ironically though some of the ME3 biotic attacks feel pretty good and weighty despite the weapons being lackluster.
Edit: Got a bit sidetracked by sound design, my bad.
