Have you prepared your 3rd sub yet, for when Tynon release it?
Are ALL your heroes SERAPH V (Gold)
Are ALL your heroes ARCHANGEL V (Purple)
Are ALL you heroes ANGEL V (Blue)
Yes, 3rd sub is prepared and equipped.
Gold heroes can only go to Dominion V.
Leader is Seraph V.
I max out only the heroes I use. No sense in maxxing out an Alexa, Smoulder, or any blue hero.
I'm not the only one like this, several players already are.
