That is true.yea but cost of buying the goods in FP's will be so high the players who will need it won't be able to aford it
Your points are good ones.That is true.
But having a GB that reduces your defences kinda makes St basil’s, deal and Terracotta a bit redundant. A 20% reduction of a 200% defence is higher than what a level 10 defence boost of all of these GBs as a level 10 only gives a 30% defence boost for st basil and deal castle, while TA level 10 gives you 20%.
Also those who choose to put in WFs or ritual flames to beef up their defences are using valuable real estate in their city to do so. Therefore, I don’t think anyone should be penalised for choosing to have a strong defence boost as it is already costing them a lot of FPS and real estate to do so.
