I'm sorry, but no. Only people who wanted to hit crafting level 100 NOW took millions and millions of Plat to reach that level. My brother is currently making those GS equivalent weapons with 8-10 hours invested into the crafting hall and having spent no money at all on items and I am sitting at over 50 in all school, all we did was Decon EVERYTHING we got. The only reason I am not higher is cause I stopped crafting after about 3 hours of crafting hall time.
And if you are counting the time you spend Deconing as part of the time you spend making shards, then you must have the most full DDO schedule ever, cause I know I can find 5 minutes between a raid and decon my 20 quests worth of equipment.
