Hello everyone! Recently I decided that it's the time I should get back to AL (actually, just got a better PC that could run AL). However, I noticed that the game changed quite a lot. So, naturally a few questions had came to my head (tried looking at the newer guides, however, couldn't really find anything helpful):
How could I make some gold with Warrior(37), Rogue(31) or Mage(24)? I have lepre, however, it seems that locked crates do not drop all that much from Jarl and I had never tried running KM3 (are they worth looking at?) I noticed that there are that Dragonite bar, which looks pretty expensive, however, I have no idea how long would it take for me to collect all the tooth (maybe anyone know estimate? And maybe it's faster with rogue?) Would be awesome to learn the price of it as well, there are none up in auction house.
Is it worth going mad in KT4 with all of my characters, or should I go to Tindrin for teeth, after I can?

Any tips regarding game changes since 1.5 - 2 years ago are appreciated as well!
