I was thinking that the XP Boost is a great feature, but after 1000 Salvage, it gets a bit steep of a price, and I think that me and many other people stop at 1000 and wait until the next day. However, this means you need to try and pick the hero you want along with your orders strategically, but what if the XP Boost system as it is remained that way, but instead of including every hero, each hero is accounted for for the Salvage? The Salvage system that is in place where all the Salvage is put together in one pool should stay, but you could use the Salvage to boost all of your heroes instead of essentially a maximum of 2.
