Change boss drops, to a badge, or points, make it so each week, players can earn
" X amount " so each week a player can Know, when and how soon they will get the next gear for a slot, this way you can track and know when you will be ready to raid, reg or heroics, and no waiting for luck of the RNG item drops, You can keep 3 "tier" of Items, Just like the pvp loot system, People pvp to gear up, and you can tell how soon you will get a new / better item. If you set up All PvE on the same style system, Justice points can give full LFR / LFG item lv loot, Valor can give Reg raid ilv, and a new heroic points can give heroic Raid loot, just like the "tiers" of pvp gear each season. This way people will raid, to kill bosses, Not just show up for 1 or two bosses and leave cause they didnt get "lucky" on drops. the PvE progression curve will be a lot more trackable this way, Even if i know i only get 1 or 2 items a week, and it will take two months to gear right up, at least i know exactly when i will my 'New shield" or "trinket" and not have to wait 3 years for a random drop. Say leave the lowest "tier" of the PvE loot to be Fully open / farm-able. so a player can gear up in the "start of game blues" to get into harder stuff, sooner and more regularly, Some of you might not like the idea of not being able to "get lucky" and get 4-10 items in a week, but when you see your raid as a Whole moving along, you might change your mind.
