I can only hope NTC has been proposed due to somewhat irrational reasons such as revenue being lower than budgeted and needing a quick fix, or shortly being sold and needing to boost revenue or about to pump and dump the game.
Anything else is grossly misthought and a terrible, terrible idea.
I understand you want to maximise your profits and that, I suspect, existing core customers are your greatest revenue earners. This proposal undoubtedly in someones mind, and perhaps on an excel spreadsheet, sounds awesome to bump committment and money from that segment.
As one of those people who have spent >£4k on WG products, undertstanding I'm just one point of view, if NTC is delivered in practically any format I'm afraid I just will, with regret to my clan and the game I love, go elsewhere. The time required for most normal people to be proficient and competative in all ships will be destroyed for me.
Please, please, please think of other ways of generating revenue, rather than this and keeping people "engaged". I suspect it will damage your core segment so much the game will the be worst for it.
