Okay at this point i would like to make a suggestion:
1. It would be nice to get some variety in the endgame maps so that you don't always have to see the same thing.
2. It is very difficult (requires a lot of toca) to safely get your mastery set to a higher level > +9 to +11 without risk and then convert it to the next set tier
and you need do this 6 times at this moment to reach the Brilliant set (the first set tier doesn't count because you only need +9 to reach Dark Angel).
Making wings safely has also become much more difficult and it now takes w3 +13 to make w4, so all of this requires a lot of toca too.
That's why my suggestion is a map e.g. Altans Abyss similar to Red Smoke Icarus but instead of Guardian Pet itmes drop there at the same rate toca and etoca.
