I think there are two features of the game that need to be reworked, astrals and guild skills. As you level up a red astral, the value should go up as well. The value for a level 1 red PATK is +288, right? It is the same for level 2 and so on. Why should it stay the same when it costs so much gold to upgrade as you get into the higher levels? If you are spending 10 times as much gold to make a level 7 or whatever, the value of that level 7 should be higher.

The same goes for guild skills. Why should you spend 10 million gold to make a level 10 skill when it raises it the same as a level 1 skill? These two things do not make any sense to me at all.
