Guild Wars 2

The attack chain is Prep Thrust > Brutal Blade > Rift Slash

however,
Prep Thrust requires melee range,

and then say you’re slightly out of melee range (say because your opponent dodged away), Prep Thrust changes to Brutal Blade

but, Brutal Blade can now be spammed until the first red blade travels and actually connects with the target, this means that I can have up to 3 Brutal Blades (probably more with quickness) on the go until 1 of them hits something, and all 3 will hit twice.

(aside: you can also queue a second brutal blade even when the first connects before the second casts, and so can acheive this near melee range)

Only when Brutal Blade hits something will it change to Rift Slash

This can be fixed by changing BB>RS on cast rather than on hit. I imagine there might be a similar problem if there are any other ranged on hit abilities, allowing them to be used more than once.

I noticed this as well. Several auto chains work similarly. For example, with ranger greatsword you can get a double evade frame if the third hit misses.

I’m not sure if this is game breaking, but I wouldn’t mid either way.

Exactly, it isn’t game breaking because I feel each strike in a chain is supposed to have roughly equal value. However it does seem abit more obvious/buggy with Revenant because of the red trails
