I personally don’t like being in combat that slows the speed.
1. Then don’t get into combat, the AI in this game is so bad you can often just avoid getting hit in the first place
2. If you get into combat and are using zerker meta build you should be able to kill the mob very fast or just run away to oocPvE is not an issue at all, why on earth would it be.
Its more of a WvW thing where one thief or warrior or ranger will hit you with one shot and all there buddies who are not in combat will catch you and jump on you like an animal in heat during mating seasonSo, working as intended?
Only anet can answer that.
Call me old fashioned but I would rather have player skill like using criple, chill or immobilze as the mechanic of slowing someone down than an auto attack hit.
