It's great to see things moving. While I appreciate the modernization changes, there is so much stuff to work on.
Rebalancing is crucial. People have been using the same loadouts for years now, I rarely see any variety in endgame missions.
We NEED something else than FSC, the game just gets boring at some point, it's an endless FSC farm.

I don't think an armor rebalance would even be possible in the game's current state. There are just so many armors and not enough ways to differentiate them. To make every armor have a viable niche, the game would need a complete overhaul of the armor system. As it stands, actual defense doesn't do enough to mitigate damage to ever be worth paying attention to. The way player damage is calculated would need to be completely rewritten to make them a meaningful component to balance. Status admittedly does make a difference, but I frequently find that one needs to hard commit to specific resistances to get any real value out of it. Bonuses like ASI, CTR, MSI, and DB are too small a selection of bonuses to really be distributed well enough. Really, we could probably just assume MSI doesn't exist because I doubt we'll ever be graced with an armor set that gives a substantial MSI boost that wouldn't cost exorbitant amounts of money to access. Bonuses specifically would need like at least a dozen new options to really make a difference in balance. They'd all need to be pretty creative too in order to avoid treading the same ground as one another.

Right now, I think if anything needs to be rebalanced it's weapons. Armors are way too big of a task to ever hope of making meaningful progress in fixing right now, but there are a plethora of weapons which could be made reasonably viable just from some relatively small tweaks or bugfixes.
