I agree, something should be changed, I did 10 TI today and only got 0 ninja tools, this means that actually it's almost impossible to level up ninja tools or use ninja tool essence to put gold stats on the best tools since you need 6 tools to have a 100% success rate.

Please, give us players a way to get more ninja tools again, I suggest to give a fixed amount of moon scrolls for every Team Instance made (like 300-500) while giving again ninja tools like it was before. Otherwise you may follow the suggestion made above by Bacoked to put ninja tools in the moon shop.

I hope you can help us, thanks.
