The main problem was always that demand was so much higher than supply for certain items.
240+ supple bots
Gocs
Certain intel symbs
As for credit sploits. Idk anything about it so I won't speculate. But here is how we could fix things.
1. Limit froobs to 50m 1-49, 100m 50-100, 200m 101-150, 500m 150-189, 1 bil 190-200.
This really messes up cred Sellers. Start banning their mules and it will be very tedious for them to level up to be able to keep creds (same thing for sploiters). At the very least this will raise prices A LOT ig. Which means the amt of credits ending up ig is less.
It also nerfs those who may have 12736131 sploited froob accs probably with level 2 toons to keep all that cash.
This way you can give some notice also, so that real players don't get so much affected. Real players can move their creds off the mules to paid toons and GMI. The cred sploiters and Sellers have nowhere to go, unless they wanna get paid accs. Which would be very risky and expensive for them.
2. Add loot or increase droprate on the follow instances/mobs:
APF 13/28/35 - Add 1-2 240+ leadbots per boss. Also add a small World buff that adds 50 dmg and buffs some weird stuff such as tradeskills, and maybe 5 to abilities. :> This will get these instances running A LOT!
TNH - Make it drop symbs who doesn't drop off other pb's ONLY. This will increase the chance of phatz hugely.
Tara - Increase drops on igocs and rbp's as well as the phat nodrops. Now it's not uncommon to have 3-4 raids with just crap loot dropping. Also add a small World buff that gives yet another glow, but not really any phat skills. Maybe green. :>
Sector 7 - Increase loot chance a bit for all bossese to revive this instance.
There, I fixed it all for ya!
Also.. This is a bonus.. but..Make a HUGE monthly pvp AND pvm event in 4 holes a la gauntlet with the main reward being the winning side gets to rule 4 holes for a month and some phatz such as ELLTS and pionner bp, dillon armour :> It wouldn't have to be anything super fancy looks wise. Just a few bosses a la gauntlet and then you get transported to a waiting area IF you make it inside a certain ammount of time. Then the gas changes from 100% to 25%. And when there is only one faction left standing, a main superboss spawns. Either to congratulate the defending side or to kill for the side on the off. Both get loot.
