Currently these are kind of stuck behind a huge ballache of a minigame. No one plays it and it takes a huge amount of games to play to even upgrade each aura to level 4.
So im suggesting adding these to a more appropriate location being the PVM shop..
I do realise you can gain a huge amount of points easy so therefore these will be at a very high cost for each upgrade, increasing for each level you buy.
For exmaple:
Attack Aura level 1 = 500K Points > Level 2 = 750k > Level 3 = 1.5M > Level 4 = 2.25M
Leaving each aura totalling up to 4.5M PVM points.
THOTS?
