Yeah and even the "find the object you need" from the set is a really nice implementation..I like the Set Bonus mechanic. Its brilliant.
Why is it so? Because you can't just dump money, get a 5* weapon and start facerolling everyone. The bonus stats from a full set of 2* or 3* gears still win over a single 4* or 5* gear. This force ppl to progress at a reasonably controlled pace. Giving f2p/new players a better chance against others and more time to acquire stronger gears, since the power gap is narrowed and moving in controlled pace. Not throwing cash down and fly straight to the moon. :p
Usually people are forced to go to wiki pages and forum over the net only for know where is the X item, but like that everything is a lot more smooth
