I'd be fine with changes so long as they allowed me to pay to change an FC plot into a personal one. My house is an old FC plot that was given to me by friends who stopped playing the game back in HW but that was established in ARR. For most of SB I was sitting on the plot, waiting for them to come back, and it wasn't until ShB nearly dropped that they definitively told me I could have it. Which missed the cut off for easily selling a plot and then quickly rebuying it as a personal. I'd more than happily pay the purchase price or more to switch.
