Yeah a more traditional character progression circa Diablo 2. Does Bungie want to reinvent individual game mechanics or use existing mechanics in new and interesting ways. If they had ghost deployable items such as physical protection- [your cabal tower shield]/Defensive Turret (Autonomous|Manual) would we think theres a re-used Bunige mechanic from Halo 3 or there's deployable items similar to either from halo 3 or Bioshock Infinity dimension ripping mechanic. Within Destiny we've seen Bungie transport the Gate Lords Head already ghost either short range teleports (from your ship) or carrys it itself. If bungie won't let us sell planet mats to the tower maybe ghost could construct them from our inventory Protection (20 spin metal) Manual turret 10 spinmetal/10 helium/10 Relic Iron if it gave use more interesting ways to combat the darkness would Bungie care if it's a mechanic that has existed in the gaming industry previously if we're participating more enthusiastically. Microsoft used the Diablo 2 progress mechanic in Dungeon Siege 2 after all.
