So the intent of the Warforge / Titanforge system was to give players the ability to perhaps find an upgrade from doing ANY type of content, whether it be WQ, Dungeons, Mythic Dungeons, LFR, Raids all the way up to Mythic.
The system as it stands now kind of devalues the higher raiding echelons especially with how frequently an item can warforge / titanforge.
Could the system be changed to still give players who don't do the highest difficulty / highest form of content the feeling that they can get an upgrade from any source of content that THEY do, without it feeling like a penalty?
So for example, lets say the warforge / titanforge system will allow ANY content below Mythic raiding (and a certain tier of Mythic+ dungeons) to be able to titanforge up to ilvl 895. But if you then participate in high level mythic+ dungeons, or Mythic raiding, the gear then starts at a base ilvl of 900 and can titanforge up to 925.
With this change, it would still feel to all players (even mythic raiders) that they can find upgrades for their character from any source, but also leaves incentive for people to really push into higher end challenging content, because if a mythic raider really wants better gear, then he has to be in mythic raiding to do so, and it rewards him accordingly as he kills bosses there.
Of course with each new tier of content the ilvl will be raised to match the tier, so the max ilvl titanforge below mythic Tomb would be raised to 5 ilvls below mythic tomb gear.
