It seems to me there is an internal battle at HQ over whether ViPs need to be pursued or not v. pumping Premiums for TPs. The player base certainly has its opinions. I know there has been consistent undercurrent to see better perks for ViPs by that crowd and its supporters. I can't say I disagree as I dropped my sub when I found better value in Premium based on my perception of Turbine's offerings.
In trying to think of a balanced approach, one idea I had which I think would work - and which I do not remember reading it anywhere here, so I apologize to anyone if this has been suggested - would be to allow ViP to avoid all BtC restrictions.
Any gear designated BtC should become BtA for ViP. I think this is a substantive benefit which might entice some Premium back to ViP without upsetting the apple cart overall.
