To be fair Nukie 'ol chap, no matter how well something is designed, when it comes to computer games, there will be the chance to Min/Max it.
People can gradually work out the best ways to get their desired result, but thiss is not the same as knowing if you do X then you get 2xY. I'm more than happy to have the BGS be somewhat dark as long as whatever one does can be shown to be repeatable under the same circumstances.
Right now...This is the main problem.
But this is also a fatal flaw, in that by not telling anyone how something works you can potentially have your players miss a whole load of subtle touches- or, at the same time send players crazy by testing everything to the point of OCD. FD did it with PP, and really annoyed its players. FD semi caved in before 3.3 BGS wise, and it helped smooth things out. Post 3.3 its anyones guess. In my destructive testing I've seen some crazy stuff that borders on exploits, and yet I don't know if it is an exploit or not. QA & support won't say when I tell them, so what do I do? FD can fiddle server side, but at the same time unless they explicitly say they have changed a value its rough on players as that change can equate to hours of lost time grinding away.
I hope when I get back home and play again things will be better, but from previous years I have doubts.
