"So we had a massive thread about corp tax a while ago (https://forums.dust514.com/default.aspx?g=posts&t=67713). We reviewed all the feedback in that and discussed it with the CPM. For such a small feature it was quite heavily consulted on.

The real catch with having an NPC tax rate in DUST is you can easily work around it by starting a 1 man corporation to earn more ISK. We don't want to incentivise players leaving NPC corps, we want to incentivise them playing and socializing with other players by joining player corps. It is a subtle but very important distinction to make and a good example of where just copying EVE should not be the default decision.

What we will continue to work on is the concept of group earning so your tax money gets put to good use and hopefully earns you a greater return than if you just played solo in an NPC corp. The whole being greater than the sum of the parts type deal. We also have plans to help corporations recruit more effectively and share their wealth with their members, but more on this later.

Thanks for all the comments so far."

What if corps could set discounts for their members, such covering a percentage of the cost whenever you buy something off the market? or insurance on items or vehicles that the corp can choose to offer to help soften the loss of isk destroyed in matches?

I could see corp insurance policies working well for vehicle users, while a corp co-pay of sorts would work nicely for infantry.

what do you guys think?

then everyone will join the megacorps to save isk
