Dear Developers.

No one likes to TP in their TH gear. In fact, I hate using my thief's knife, because its damage rating is so extremely low that the reduced kill speed from using it probably leads to fewer drops over time than if I had used a different weapon in my off-hand.

If you care about thieves and their thief knives at all, make a trial for it that keeps the name, but increases damage and level requirements. This way, we wouldn't be asked to equip the new thief's knife and offhand the old one, which would put us back in the same situation as before.

Alternatively, make a new TH dagger that only works if you aren't wearing "Thief's knife".
