I've done my best to explain to you the system they're designing for Legion, and given you real world examples of what would happen if they did it the way you wanted them to (which basically amounts to the reasons they won't do it your way). I can't make you change your opinion, only you can realize that it needs to be changed.
If an item is unobtainable, meaning you couldn't get it again on a new character, why would you expect to have it's appearance unlocked for use on any new character moving forward? Does that really sound reasonable to you? If you're being given brand new rewards to fill the gaps where rewards didn't previously exist for your armor type/level, why would you expect them to make it so you can continue to use the old items that don't fall in line with the new design? Furthermore, why would you expect to be able to transmog things you aren't supposed to wear?
Ever single time I respond to you, these are the questions I'm trying to get you to answer. You want things that, on their face, do not seem reasonable, given the context and scope of the changes coming in Legion.
If you have Lucky Fishing Hat on a druid, and you like the mog, what if they are adding leather, mail, and plate versions of LFH to the event so that everyone has a reward? That's what you need to understand is actually happening. Yes, your cloth LFH won't be useable on a druid. But if they add a new leather LFH for parity (which is what they are in fact, trying to do across the board, but will take time and not be 100%) why don't you just go get the new LFH in the appropriate armor type for you class, and use that instead of continuing to make a big deal about your cloth hat?
This is just an example, mind you. I don't know if the extent of their changes will reach that far. But I can tell you what stuff like this looks like at max level, and it's not bad. If you like the monk helm (rice hat mog) it comes in 4 different armor types as a white item with no stats. You just buy the one you need and you're on your way. Instead of whining about changes, maybe make suggestions based on each case usage you've found. I guarantee you Blizzard will be a lot more likely to go 'yeah, there's not parity with STV fishing rewards, we can fix that' than 'yes, well go ahead and break our rules so you can continue to value your Cloth LFH.'
There was even a thread asking for players to suggest items that don't fall in line with Legion design so they can be addressed before the expansion drops. Go find that thread and fill it with suggestions!
Also one more post to actually clear up what I'm talking about, I'm not talking about what Blizzard described will happen or what they want to do, I'm talking about what is on PTR right now.
You currently don't unlock any quest rewards from quests you've completed already, unless you have a physical reward from that quest, in your bags. Say you have a quest you did two days ago, with an axe and shield as reward, if you deleted the reward, none will be added to your wardrobe coming Legion. Only if you kept the shield or axe, will both rewards be unlocked.
That probably has more to do with the way PTR now handles characters and account wide stuff (it doesn't, really) than the specific transmog system for Legion. Like, if I copy my main toon over to the PTR, none of the toys or heirlooms I've collected show up. I have to re-add everything to the UI manually because for some reason, those fall through the cracks of character copy on the PTR.
It's not a big deal and it's not something that will happen on live servers. You have to understand that these builds for the Beta/PTR are created from scratch by the build team before being deployed on the test servers. They're not taking a live version of the game, modifying it for the test servers, and then moving it back to live server once it's where they want it.
No, builds are stand alone and every time there's a maintenance or patch, a new build is being created from scratch and being deployed. You can probably expect a more robust catalog of items to be available once these changes hit live servers, because the game won't have to rely on character copies to track items. Those will be tracked account wide before launch and upon login on patch day, added just like they have been in the past on live servers - which is not the case on the PTR or Beta realms.
I still wouldn't expect them to let you use GF'd items or transmog the wrong armor type for your class.
