Guild Wars 2

(1) The Shadow Arts thief trait “Cloaked in Stealth” is described as “gaining stealth blinds nearby foes”. However instead it pulses a blind every few seconds when in stealth seemingly. The thief has no control over this while the trait is on. This might not be a problem except ….

(2) Blinding any creature, even neutral and ambient creatures, will put a character into stealth. If the character is in stealth then the creature will not itself start attacking though and it can actually be impossible to tell which creature has put a character into combat without randomly killing everything. Ambient creatures never show they are in combat. This leaves strange situations where characters are standing around with in-combat run speed, unable to change traits, unable to change items, unable to change skills, unable to use waypoints, and reviving at half speed, all because some unknown creature was accidentally blinded by stealth. The blinded creature seems to get no defensive benefit from putting the stealthy player character into combat. It is a pure coincidental disadvantage for the character created through game mechanics.

Put (1) and (2) together and you get thieves running past creatures using stealth and being put into combat by accidentally blinding creatures through unpredictable mechanics. Out-of-combat run speed is lost when it is most needed. (1) seems like a unintended feature but it wouldn’t be a problem if it wasn’t for (2). Fixing (2) would remove the major problem of (1).
