To elaborate on the
Honour Mode unlocking transmog appearances account-wide;
Larian would most likely only consider implementing the transmog feature
as a per-playthrough feature; meaning the player would only get to transmog what they collected
in that current playthrough.
And one thing I massively dislike about RPGs is when the most captivating-looking equipment the player wants to roleplay with is all locked away behind ACT 3's late game, at which point the player only gets a few hours to enjoy them before the game is over. So to enjoy the [Elegant Robe], [Wavemother's Robe] or [Mutilated Carapace] which are all late ACT 3 items, the player only gets to do so for a few hours before the game is over.This is why the
Honour Mode suggestion was made so that Larian at least considers an
account-wide appearance system, similarly to the
Golden Dice being account-wide;
- The transmog would naturally be available from the very beginning on any difficulty as a per-playthrough feature. Meaning they're able to transmog only the equipment they collect as they play through the game.
- But if the player for example wants the appearance of [Wavemother's Robe] from the very beginning of a playthrough, they'd have to obtain it in Honour Mode first to unlock it account-wide for all playthroughs.
NOTE: I only made this suggestion incase Larian or other players wanted/needed some meaning behind an account-wide transmog. Personally it doesn't matter to me how it's implemented, I just want account-wide transmog so I can roleplay my characters throughout the entire journey, not just the final 5 hours!
