The Phoenix Faction are too powerful for an early game faction. They are essentially invincible unless you get super lucky with stun procs. They require no skill to win with. They allow their characters to heal when they are attacked which makes no sense. They are too easily accessible. They provide the game with a, “If you can’t beat em, join em.” mentality, which is extremely bad for a turn based strategy game that is all about collecting characters and trying out different combos. From what I’ve heard the Phoenix Faction stops being good at about gear level 7 or 8 compared to other factions. But it’s awful all throughout early game/mid game, where they are nearly every team you come across in arena.
Also I must point this out, if the argument for having them in is, “Just learn how to beat them.” Then the point I am making here has been missed. This team is nigh impossible to beat early game - mid game, no matter how good you are. I have beaten my fair share of Phoenix teams but it’s usually only because I got lucky with procs.
It is ok to make a team powerful or good, but there is a line where a team goes from being good in the right hands to being absolutely overpowered and stupid.
