Tc20 just turned out back to back purple, domitia and obakan. My only other 5s are joon at 3.70, vivica at 3.70, (1 dart and I can take 1 to 4.80), Elena and Khagan(I can take 1 to 4.80) and most recently the 2 purples. I’m leaning toward domitia but obakan is fast mana. I can only take 1 to 4.80 the other has to sit at 3.70.
Any opinions? I would like choices for:
Joon vs. Vivica to 4.80
Elena vs. Khagan to 4.80
Domitia vs. Obakan to 4.80.
Thanks.
Also tc20 holding at around 5%. Latest popped out at 92,93 and after that I’ve gotten a few more 3s and a 4 but its right around 5% for stats(joon came from summon, rest from tc20).
I’d take Joon to max since attackers only shine when fully levelled. Viv’s heal doesn’t require her to be maxed, and I was using her in war right after she hit 8/8 on her special. Stick her in a corner for raids and war, and hope she doesn’t get hit by a sniper 
Between Elena and Khagan, I’d pick Elena. In defense, I’d use her as a flank, but only on a mana steal/drain tank like Onatel or Guin due to her having slow mana. Another problem is that she has low defense and health. Khagan’s defense and health are better but still not good enough to tank. However, if you need one, he’ll do till you find a better hero. Just have to hope that he gets a chance to fire before he gets killed.
For purples, I’d go with Domitia if you choose Elena, and Obakan, if you choose to max Khagan. Get both to 3/70 first and play around with them for a bit. You’ve only posted your 5*s here so not sure what else you have on your roster. Don’t ignore the epic heroes. Some work better in defense and offense than a legendary at 3/70, e.g. Rigard.
If you tend to do pulls, I’d wait till the next Atlantis and see what heroes show up. Word is GM will make an appearance soon and he’s definitely the one to get as he’d make a great tank for your team.
