I think I should be graduating (or close to graduating) from newbie status now considering I have played this for about 4 weeks... total power is about 25k for Thunder team, with a few level 1 weapon so I think I have lots of room for improvement once I start to enhance those weapons. I think by the time I level all those weapon, I should be close to 28k which should be enough to let me do Ultimate.
If my thunder team doesnt cut it, I can always go back to my water team which currently have about 30k power. It will probably be lower though cause I'll have to replace Amaterasu with something else.
