Space legs links to that - the amount of time and situations where EVA/boarding are actually sane actions is really really low. Leaving your ship is nigh on suicide in situations where other ships may be about - a rail gun to the chest is nothing to laugh about. For the quantity of work it entails it's usefulness seems quite low - especially stations and cities where it's mostly making a super-quick menu interface into a long meander that'll quickly tire
I think this is true if
- EVA is only used in ship-to-ship combat situations
- You are always trying to destroy your opponents and kill everyone on board.
I hop these things won't be true.
