As the title says, I think Wrexsoul was absolutely awful, and with no real way to escape DreamWorld before going through him...he is really a hardgate.
I think the most frustrating part of him is just how fast his adds are. They already hit hard, and it can be mitigated decently, but their speed is insane. I really believe that needs to be toned down a bit.
Hell, trade speed for more damage (since Wrexsoul gimmick is someone dying anyway). It would at least give some breathing room.
Instead, a bombardment of AoE is just hard to keep on top of with only three characters.
Though, one thing (unless it's hiding somewhere), is adding another ghost (or changing item shop ghost since he sells nothing worthwhile anyway) to remove party member equips instead.
Having access to my full equipment pool would have helped immensely in properly prepping for the fight since party re-arrangement after entering is completely out of the question.
I will definitely say that this is the first fight I've thoroughly hated.
side note, Bushido GoGo with the right party is MVP. EMPOWERER.
