First off, nick's announcement is here.
My first thought is how this will be represented with armor defense values. Only because these are the only number values we can see at a single click as opposed to relative value power meters. Will we actually see the numbers in our equip screens change to reflect this?
Otherwise I do think this is probably a good idea, it is boring fighting down from Haven with high tier equipment when your elevator pass expires.
I agree with the changes, as a challenge is always fun, and will make it more friendly for higher level players to run lower equipped players through the starting gates (though it still won't be worth it in terms of crowns and heat). However, I am confused by the statement that says "What this means is that an item will increase in power the closer it gets to the core." Does this mean items will get stronger as well, the farther down you go?
