Just made it to level 50.
A few things I thought along the way.
Primary weapons don’t really need a buff, they just need to add-in the perks that the first game weapons had. Then if the weapons are still out of balance then a buff would be more proper.
Some support weapons definitely need to be more in line with the Railgun. I understand the Stalwart and Machine Gun not have anti-armor capabilities since they are early game weapons but the rest need a buff in how much damage they do to armored enemies.
Armor needs more variety in the passive perks they have.
Helmets would be cool if they had passive perks as well, maybe like an infrared, thermal, night vision or maybe that could be on scopes. Or something like scans area of x amount of meters for enemies every x seconds.
High level difficulties should count more towards the liberation of a planet.
I will update this post as I think of more
