Team Suggestions (moved)

Hello, all. I am hoping to get some help with a few choices for my team.

Current Lineup (back/front):
lv79 Awakened Nexara               lv77 Awakened Mystery man
lv75 Candy Can                         lv77 Master Wu
lv90 Adept Rhee

My main plan was to have awakened MM for stun 1st turn and regular Wu for stun 2nd turn. Before I was able to get Candy Can, my damage output was kinda meh. I have had horrible luck with pulling hunters my entire time playing.

I also have available Estine, Tao Yuan, Edvard, Awakened Merila, Sir Rogas, Hanzen, and others.

Should I swap someone out for Merila, perhaps? I will have my first 40k courage gems later today.. Should I go for a courage hero to replace someone on my team? Also, a few x11 SSummons down the road, I will have enough pink gems to grab another of those heroes - I was planning on getting Glax to replace Wu, but extra output from a second Candy Can might be nice.

Trying to work on spinning an Aelis as well, but only 4 pieces so far. Also, having just joined up with a guild, I am getting pieces of Royal Maske.

So um, yea. Anyone want to take a whack at this one?
Thanks, guys.

Yes, this is a relisting.. seems I posted to the wrong subforum.

Trade Nex for Merila. I dunno what lvl you are, but if you're high enough to do labyrinth, Sir Rogas helps a lot. I'd suggest getting Glax and running him with Rogas or MM, if you'd prefer the stun.

I just today reached player level 102. Thank you for the advice   

I do hesitate on changing out Nex for another mage since my Rhee is in need of mage evolve mats..

As I have enough courage gems, I was actually thinking of switching out Nex for Marlina. That would ease the mats requirement on Rhee since Marlina is a hunter. Merila seems like she has much better crit stats than Marlina.. but I was also liking Marlina's dodge chance..

If I don't go for Marlina, should I just buy up 418 courage chests and not worry with courage heroes?
Thanks again~

Nex and merila are quite similar, I switched my nex out for merila thinking the damage output would increase but I found merila's damage to be a lot more inconsistent, however she doesn't get block countered, if i had the option i'd switch her out into marlina but thats up to u to see whether its worth doing or not, id worry more about the front line atm
