Greetings, Reika!
Thank you for posting your concerns about the Gladiator HP. In order to make sure that we have sufficient information for a thorough investigation, it would be a great help to us if you could provide the names of the pieces of equipment that were on both of these characters that you have tried this with. As soon as you are able to provide this information, we will make sure that all of the details that you have posted is submitted to the development team, and they will try their best to replicate what you have been experiencing. Thanks again for your participation!
