Not really. The prices are going down, but the quantity you are bringing in just went up. As long as your market can absorb the increased number of frost lotuses you'll make about the same amount of money. The issue will be if the increased number of frost lotuses are needed or not.
Also you might see a significant increase in Icethorn, Lichbloom, and other flask required mats because those drop rates didn't go up.
Personally I sold 200 frost lotuses yesterday for 60g/each. They have been going for 70-80g each in the past week prior to the drop increase and they basically completely stopped selling for a few days when the announcement was made. Now they are back to selling at 50-60g each, but I'm also picking up about 4-5 stacks a day now.
I don't know about you guys, but I'm raking in the gold. I'm probably pulling a good 6-7k/day right now with just a single bot.
Expect the prices of Frost Lotus and Titansteel to go down, but other goods will go up.
