The amount of these we’re getting is disgustingly low. 50-80 per dungeon depending how many bosses there are, I dont want to do 100 time walking dungeons to buy a reward thats time gated for this week only while the vendor persists.
This anniversary has been a fail regarding the currency, no1 wants to camp time walking dungeons to buy all the rewards. Yeah the coins can be turned to the badges but after that you either need an Alt army to farm or just sit in timewalking RDF. It’s insanely bad
The timewalking vendors are present during their TW-week, they will return, their storage won’t change - for years, based on what the vendors currently have. You don’t use time warped badges for anniversary stuff ( they cost Bronze celebration tokens).
If you have many alts. It’s much easy get more TW badges with quest reward and warband 's currency transfer
What?
Low?
What are you even doing in-game?
Really, really not. There are daily opportunities to earn badges atm. Whereas prior to the event, and again once the event is at an end, you can earn a few hundred per character every three weeks. If you think the current rate is bad, then just wait till it goes back to normal.
Blizzard seems to think that every player has an alt army. If you have only one character you can grind for those things for ever.
You can also buy TW badges with anniversary tokens. 500 badges for 25 tokens if I remember correctly.
To be fair, the new TW rewards are permanent additions to the vendors, they arent going anywhere. If you miss them this event, they will be back for the next. I dont think the point is to get everything here and now, but to have rewards to work towards throughout the foreseeable future. A lot of people have been starved for TW rewards for years at this point, because there weren’t that many to earn in the first place, now they added more, so people once again have rewards to earn.
What? So you would rather have the old system of 500 per character, where it wasn’t transferable? Oh you want the mount? Yep, better grind the heck out of the runs or wait a few cycles…
Like damn, calm down you don’t need to empty the vendor in its first cycle 
If you do, you’ll probably come back and make a “omg Blizzard when will you add new stuff to TW vendors??? Badges are useless currently!” thread
