The change, which guarantees you'll be at least five levels lower than the guards, takes advantage of existing game mechanics to protect lower-level players from mischief. NPCs that are five levels higher than you are exceedingly difficult to hit (spell casters will suffer a 39 percent chance to miss) and frequently wallop you for higher-damage-causing crushing blows far more often. The guards will also have higher health pools as well. This contrasts vividly with guards on the live server, who are prone to dying if a level 80 character accidentally sneezes on them.
Level 90 guards are better suited to protecting newbie players from max-level griefers. Note that only starting areas will see these high-level guards. The guards in major cities are now level 85 -- dangerous, but soloable.
Players who are upset by this change are encouraged to stop being jerks who grief newbies.
