These items are fast becoming staples in the new update.
They provide a too big an advantage (the health module especially) to whoever's wielding them. Since they can only be found as legendaries, they're too hard to come by for most players. My suggestion would be to make these items epic/legendary/mythical to bridge the large gap between these and their 'Epic Max' counterparts.
If these items continue to be legendary only items, we're going to have a repeat scenario of the God Mode, heat control etc. days.
