Interesting 3.3 Dungeons Tidbit

[Shodokan]

Random LFG gives badges per boss + 2 at the end + 13g each character.

So for every random heroic you do... you are guaranteed 5 to 7 badges. Assuming you can do 2 OG heroics per hour with "ok" gear that means you get 10-14 badges per hour. If you can do 3 per hour that is 15-21 badges per hour. If you are REALLY good... you can get 20-28 badges per hour.

Considering t9 takes 190 badges that is...
15 hours (with OK gear) - 12 per hour Average
10 hours (with medium gear) - 18 per hour average
8 hours (with t8 or better gear) - 24 per hour average

After each run you get 65 gold total not including DE + selling greys + gold from drops. So you are looking at... minimum of 300 gold per heroic.
