The elevators cost 10 eng. That makes people dont care if they go alone or group.
If the cost whold be divided for every one, making the diference being up.
Ex.: group of two, elevator cost 5 eng each player
group of 3, elevator cost 4 eng (beacause 3 plus 3 plus 3 equal 9)
This will improve player grouping and socialization.
p.s.:sorry the bad english
The current system is fine. If you want a party, it's already VERY easy to join one.
Decreasing elevator costs will only increase the price of CE and make it MUCH harder to buy for anyone who doesn't play in a party of 4. What you're suggesting won't encourage partying; it'll force it.
All this will do is ruin the game for people who like soloing or even just playing with one or two close friends.
