Why does this game lack features compared to MWO?

MWO has better visual modes that provide actual clarity, not a blurry mess of green filter.

Consumables / added tech you can launch for better radar and stuff.

Weapon jamming

Higher weapon variety (I understand MWO is probably several centuries ahead in lore and also has Clantech, but nonetheless)

Proper urban zones / city / sci fi space maps, not isolated blocks of land inexplicably in the middle of nowhere, with loads of wasted space and badly generated terrain that isn't properly utilized*.*

Hell, the mech sounds are more vivid. You hear your reactor buzzing all around you. The judder and thud as your robot stomps forward. Machine guns sound like heavy caliber guns, whereas in 5 they sound like the light pink of spent staples landing on tinfoil.

The HUD has more information, though it is more cluttered.

How is this game they've been developing alongside their online installment lacking in so much, and so stale in comparison? Why do we have to rely on modders to fill in all these gaps?
