Hey people! I'm new to the forums so please let me know if this isn't the right place. Also English isn't my first language but I'll try my best!

I'm kinda new to the game, I'm playing for less than a month (I've tried the game at launch but only a couple of days, I still got the account tho)

So, now I'm level 28 and this is my progress so far:

I have some 5* characters, but my main team is Samurai Eddie, Wrath, Gunner Lilith and Clairvoyant (thanks to some impulsive frontier purchases), all level 65~70, 3* talismans.
I've reached night city, completed the first 2 world's on all difficulties and others on normal and hard. I'm at stage 6 on brave New world and Lord of light dungeons, reached acolyte 1 on arena and rank B on gauntlet.

Now I'm stuck, I still can progress a little on madness battlefield and underworld hard with troopers, but I can't reach higher stages on dungeons or better ranks on arena and gauntlet.

What should I grind now? What should be my goal from now on? Please help me on my next steps in the game. Thanks in advance!
