At level 80, a lot of people are trying to make gold in Northrend, if you are a rogue, I think you can take it in other ways.
In TBC, many rogue farm Mana-Tombs, almost 300G per hour. We can still do this.
All you do is sneak, go up, sneak attack, and keep slashing. Unfortunately, BLZ designed a copy of the access restrictions, one hour mana grave can only be brushed 5 times. So how much is the income each time?
Let's calculate it
A chest can provide you with an average income of about 6 gold, a single brush is 12 gold, and five single brushes are 60 gold. Monsters also drop quite a lot of silver coins, with an average of 30-80 silver coins dropped by a single brush.
It is estimated that the income of once is about 10 gold, then five times it is about 50 gold.
Mana-Tombs has a large amount of deposits, even WotLK still has its unique value, five times will give you 40G income.
Let's calculate the earnings for an hour:
60+5+50+20+40=175
In level 80, you just need 5min for once Mana-Tombs, that means you will get 175 gold in half hour.
The other half hour, we need back to Northrend, in Sholazar Basin, there are many undead army, refresh time is very fast
Rogue can steal silver coins from them, 4-25 per undead. This will give you 120 gold in half hour.
Precautions:
1. Glyph select increases Steal by 5 yards
2. Glyph select chest opening time reduced by 100%
3. Hearthstone set in Dalaran, very helpful
