So I've kind of fallen on hard times so I have decided to come back to Runescape and use bonds to pay my way. However I have been told the normal money making system has changed. I have about 20mil and all the T70 gear as of now

Herb farming is still consistent cash. It's not hard with most herbs to make 150 k ish profit per run. MTK is also still profitable so get that going ASAP. 

Your DG is kinda low so I would personally work on that while herb farming for some extra cash and getting chaotic claws.

 

 

If you've got t7 wand/book and glacors unlocked they're great magic exp, charms and profit. 

 

Slayering is going to make petty cash with the occasional sirenic scale to help things along.

 

Between slayer and (potentially) Glacors you should be good, most of your stats are sub 90 for combat which is when you can get the weapons to really start boss hunting for cash. 

 

 

By t7 gear do you mean barrows or GWD? Because the two are very different. If you have barrows that'll be fine for most things but you're going to want to switch to GWD sets for the damage boost for most things asap. Also what kind of weapons are you looking at?

 

TDLD: Herb farming with DG for now, then slayer/glacors to train stats. Then boss hunting.
