The one free waifu (and hero shards being readily available) is huge for f2p gang, I was able to get deb and her dupe without ever pulling her in the gacha. Here she's just in full effect, if I got crit in the first round and left him over 50%, he'd do lightning attacks that only hit her and because she's resistant to zap I can still win reasonably from that. With this team I've had a 100% success rate for the 2 round fight, doing it in a single is pretty much limited to the biggest of whales and I'm still 100% f2p, so not even gonna touch that.I really went overboard with grinding up for this fight, cause I know it's one of the last I'll do. That made it really easy and disappointing though.
