Shazbot and Klaas could use a revamp because almost all of the things they give are obsolete. You can get free elixirs that are better than the ones Shazbot and Klaas provide by watching ads. The pets they give can be obtained for very cheap in auction.

Here's a small list of what can be done to improve them:
-Make the elixirs they provide stack and not countdown in towns
-Provide a much wider variety of currencies
-Provide low-tier jewels
-Remove pet eggs from their loot pool

What do you guys think should be done to improve them?
