And now below i will say what disappointed me in this whole instance.
The reason I am disappointed is that the last boss is... actually there is no actual last boss, i was hoping that after killing all 5 elemental guardians some big doors would open to the last mighty boss but... nothing, it made me feel like, not 'go there to stop xxx' but it felt more of 'clean whole place, leave nothing alive' (what we do normally any other way but still...)
What do you guys think about it.
