Won't someone please think of the Krabs!

" unsustainable amounts of ore ".

If we are not blowing up enough stuff then this will be a problem. Bring back the daily cap on Ore per system and you have a control lever to manage that.
.

" High Sec loot surplus ". I heard this recently.

Tech 2 comes from Null. Meta 8 often comes from Null. No-one uses Meta 6. Well, not much anyway. If there is too much Meta 8 then, again, dial it back a bit.
.

" Too much VNI Krabbing afk Alphas etc. "

Make sure the Ishtar can do the job too. That would fix that. You fly the more hands-on VNI, then pair up ( or fleet up ) with Ishtars across multiple sites.
.

" Losing Local in Null. "

People who fly in Null chose not to fly in Wormholes. This could cost you A LOT of players if it is more than just an experiment for a short period of time. Make more WH systems. Don’t break Null.

Carrier Nerfs so far.

The NSA is the NSA. As you do. How can it be that a Fighter that is faster & smaller than a frigate can’t hit it? It makes zero sense. If carriers get too flimsy then no-one will fly them.
.

All of this is simple logic. But if people can’t afford to buy ships then Null falls apart. You can only squeeze so much out of Null.
