Guild Wars 2

Tonight when fighting the Jade Maw, at the end (when everyone gets the skull over there head) and used Rush (Warrior Greatsword ability 5) to move toward a reflection crystal quickly, but the game instead decided to send me in a completely random direction, in no way accounting for the fact that I was facing the crystal. This is despite the fact that there were no mobs present (visibly, at least).

The mechanics of Rush (and other charges) are generally buggy and cannot be relied up to pull off situational manoeuvres in combat. For example, if you use Whirlwind Attack to move through some mobs and instantly press Rush at the end of it, some of the time you will charge far, far away from the mob you have targeted (if you camera is facing away from the mobs) rather than return to the mob.

It’s simply not enjoyable having to micromanage the camera position in such a situation just to compensate for the buggy behaviour of certain abilities, and it really breaks the immersion. Please give the game’s charge mechanics some real attention so they start working correctly.

The leap with sword on warrior (skill 2), kind of works the same way. 1)You kill a mob, 2)select your next target, 3)press 2, and if you didn’t let a couple of seconds between steps 2) and 3), it will jump in the direction of the mob you alredy killed. It has sent me off cliffs or through gaps more times than I count, making me rage to the point of having to leave the game for a while in order not to smash the screen.
But as you said, the kind of things that will remain buggy and unreliable forever.
P.D.: In the last patch they also screwed something in target/autotarget/untarget, making combat even more of a joke.

try turn off “autotargeting” in options
