When the charges offer poor value for money, most people will decline to pay them (I'm excluding the usual suspects from this of course).
That old 20 gold for a very limited energy refill is a good one. An obvious trap for players lacking patience back in the day when we only used energy for map jobs really (and smart players learnt to only farm the best places anyway), it's turned into a rip-off as energy requirements for LTQs get more extreme and prizes get worse. Why the surprise when people turn their backs?
