In other words, are there classes that people want to play but don't want to deal with their gameplay mechanics? Such as Angelic Buster's battery or Xenon's energy? Would people be willing to play these classes if there was a nerfed version but didn't have those types of gameplay mechanics?
I would be one of the few if any who would main these classes if they didn't have those special traits even if the class was nerfed to be a lot weaker but not have to deal with stuff like that.
Think of a phantom clone version of all these classes where they can spam skills but have a lower damage output or buff an unlimited number of times but have those buffs get nerfed. Would this make more players want to make these classes?
In a way, yes. At the cost that they are weaker than playing the class normally. I'm not trying to sound like splitting these classes into a new class, but rather a way to work around these mechanics at a cost of lesser damage or bonuses (Edit: I did mean to split these classes at first but what I really want out of this is just a way to make these classes easier to work with). Kind of like aran's combo or hotkey skills that do more damage when using the combo and do less damage if a hotkey version for the same skill was pressed.
This can't work for all classes like Xenon or Angelic buster, but can for classes like demon avenger or kaiser (actually, kaiser is already like that). For Xenon and Angelic buster, if there is no more energy to use a skill, it should use MP but give a weaker buff unless a stronger previous buff was still present. As for Angelic Buster, instead of failing a skill it could just use the skill successfully but with lower damage.
If anything, this is just a suggestion to rework the gameplay mechanics of characters so that things don't happen at inconvenient times.
