I'm not sure if they changed the mechanics for roaming duelists, but does Chazz's appearance gauge reset for anyone if they switch characters? I would go from "coming closer" to "keep dueling".
Yes, it was happening to me too yesterday/earlier. But I think they fixed it for me. Also, it might be an issue if you're using regular Chazz. I was switching between Chazz and other characters. The Event Details page says you're not supposed to use regular Chazz. Otherwise, Serious Chazz will not appear, which is stupid because I wanted to level up Chazz. Someone should complain to Konami.
in canon serious chazz is the same chazz you're using so it makes sense, level up alexis cyber angels saffira is a tier 1 deck and you need those cyber petit angels and idatens
I understand what you're saying, but it doesn't make sense in my opinion because it's a game and you can already fight roaming duelists as the same character anyway. My Alexis is Lvl 40. I'm F2P. I don't want to spend gems building an expensive Saffira/Angels deck. I hit KOG last season with a budget Angels deck. It was infuriating. I'm leveling Bastion. Might try a Gemini deck for fun one day.
