Lot's of QQ'ing and "I wantz mys moneyz backz" going on here. Having personally spent around 100 mil on walls, and replacement walls, and ammo to grow them, and ammunition to blow them up, perhaps I too should be complaining about the use of the word "persistant" and demanding return of my NIC.
Then again, maybe not.
Persistant does not mean immortal. Walls can be blown up, does that negate the use of the word "persistant"?
Well, damn son, I built this wall and it's not here anymore, someone blew it up and I have to build another! That's not persistant!
And what happens in that case? You build a replacement, and when it gets blown up again, you build another, rinse and repeat. Walls grow by themselves, if you do not use the charges to grow them, and I am assuming that the growth rate is the same as the decay rate. 21 days from flat tile to full heigth wall, and 21 days from full height wall to dirt, assuming the average of 4hp per 8 hours.
When you build a house are you done? Having been a home owner, I know that is anything but the case. There is always something you have to do, maintenance you have to perform, things that have to be replaced, and the occasional broken something, or a tree falls on your garage during a storm. There is upkeep to keep your home in good shape.
The fact remains that walls, as they were, are unbalanced as hell. Instead of playing around with them and figuring out the issues and what would happen to game play, many went hog *** wild with them. And anyone who bothered to think about it objectively could have seen a mile away that some change was going to happen with them, especially if they were abused. Now you have to be willing to maintain them, and lets be honest people, if you had been reasonable in their deployment, this would not be an issue. Short sightedness will always end up with it's price.
PS- Walls are not a replacement to that which truly defends territory, an armed force effective enough to defend itself. Unfortuneately, many resorted to walls as their main defense because they were not able to effectively defend themselves with firepower or scouting out hostiles to keep assets in the field safe.
BETA = RISK, that is what justifies the rewards. Instead, you want the rewards with little to no risk. For such, stay on alpha, it's where you belong if you want no risk.
