And we had a Boss collection every 3 months. Each collection taking 3 weeks. So 25% of the time we had a boss collection. I would say that is enough.

It would be fun to have more variation in Boss stats though. Until now every boss was the same. It would add to the fun if some bosses were weaker and some bosses were stronger. A difficult hard to beat boss could give a strong Boss armor, and an easier to beat one can give a weaker armor.

Boss collection rewards have not exactly gone down through time. A long time ago the reward has been Black Kal. That is now obsolete. Then we got a cape. A cape is nice but useless. After that we got Aegis of the Dragon +. At that time that was one of the strongest non epics around. Now we got Green Kal. That is much stronger than black Kal and certainly competitive in the Legendary + category. If you can not provide 3 favourable element Legendary +'s somewhere Green Kal + is certainly a nice back-up. In the Arena Green Kal + will be as useful as any current Legendary +.
