In terms of RG, their force abilities have already been removed (excluding force absorb and blocking) due to unrelated topics/conversations.
In terms of IQ as a whole, it would be a large process of editing the damage for all the crystals and resticting health - especially how other factors contribute to how they use the equipment they get. For example, many player have donated to recieve certain items/parts that increase their performance, if we change that then we are taking away what the donation orginally promised them - also people have bought levels/skillpoints to reach certain abilities meaning it could be unfair to just restrict/remove them. In addition, the customization of their lightsabers aren't just to dominate event characters, it is also a crutial role in how they train/duel each other through their passive RP sessions. Furthermore, the Inquisitors generally follow the densive rule (as they are constantly being informed) and those that break it are usually punished (through strikes or tick reduction). Furthermore, the healing abilities also help the troopers. On the other hand, it is possible to add a time restriction on how often one can use the healing abilities (through editing the config).
In my opinion, the easier and fairer way to deal with this is to change how event characters deal with Inquisitors (like a new stun device or a weapon that pushes them back). For example, we have recently successfully coded new elctro batons for purge, meaning we can do the same for event characters without having to be Jedi. Moreover, we currently have ways that can suppress Inquisitors that I have seen to be successful like using flash/smoke grenades, jet packs, and fortifications.
