Looking at current herb prices, a perfect raid where you die 0 times yet still maximise performance. (For my class, double elixirs, haste potions, mana oils/weightstones + food) for a 4 hour raid, would cost me over 400g.
Netherbloom is 8g EACH
Terocone is bordering on 10g EACH.
That's 28g per haste potion nearly. Same price per Elixir (8 per raid 4 hour perfect raid).. Need Netherbloom for mana oils also. (4 per raid).
So, how are you affording to raid?
