Thing is, price needs to drop and lower difficulty needs to rise (read: more dedicated miners). This way the switching miner will not be interested in NLG any more. The question is where these limits are?
More dedicated miners is certainly a good thing but, as I'm sure most of you who mine NLG, as I do, are pushing the ROI limit at this point. I have watched my returns drop quite a bit in the last month or so but, NLG is one of 2 favorite coins I believe has a real future so, I keep mining but, my 20 to 40 MH/s, depending on rotation, can't compete with the multipool. So, emotionally, I will continue to mine NLG but, financially, it's a wash. Since I don't sell the coins I mine, it's easier for me to hang in there, others are more constrained to an immediate profit model.
I can tell you this, if I ran a multipool and a coin's Dev team asked me to quit while they planned an upgrade, I would certainly comply. For now, we could just ask them to drop NLG until a long term solution is found.
Just my 2 cents....
