Why are you guys always worried about how others are sand boxing? Why do you care is a corp/alliance wants to have 1 or 50 or 500 wars?
First off, no. Second, learn how it works, the war dec fee already escalates per member up to 500 million.
The formula for calculating wardec cost is (log(N) / log(1.675))^2 * 300000 * N^0.26815, where N is the number of members in the target corp/alliance. The cost is now the same when declaring on a corporation or an alliance. (1) The cost increase is in effect with numbers between 51 and 2000, where, for the latter, it reaches an upper limit of 500 million ISK. (2)
Linking the war decs costs to the number of wars is just another example of one group of players wanting to deny content to other players for their own benefit. You are basically lobbying CCP for something that benefits you. War decs are pretty much voluntary. If you don’t want to fight, drop to a noob corp. Does that come with a cost? Sure, but why should you get something the rest of us don’t and shield yourself from the same types of interaction we have to deal with.
The only reason you care about a corp or alliance having 374 war decs is you are one of the war dec targets. War decs are avoidable in a number of ways.
Reducing and limiting options for PvP in HS is probably one of the single largest problems facing the game. This trend is in the wrong direction. You simply want to take away this kind of play and offer nothing in its place.
You are aware that what keeps people in game is player interaction. That includes PvP. Further, that CCP looked at this and found that players ganked in their first 15 days stayed longer than players not ganked in their first 15 days.
Oh and before you go all pseudo-statistician on us, even CCP was surprised by this result. They expected the opposite conclusion.
The point is, war decs are probably not having a big impact on player retention…making war decs less and less viable…that probably is having a negative impact on player retention.
