WL pounce is kinda ignoring GCD.
GCD is gone at the time of landing.
it adds next attack at the same time of pounce hitting target. plus AA.
3 attacks in instant from player.
and pet.
Brutal Pounce is not affected by GCD.
it produce too much burst in 2sec.
after 3sec time frame, it's normal mdps but burst already happened in 2sec.
bigger problem is 1.1s GCD.
you can hit b4 pounce.
here is prove.

armor debuff hit first b4 pounce.
all you need to do is timely pressing skill in 1.1s during pounce fly time.
not always work but not hard to exploit neither.
3 attacks instantly, sometimes armor debuff first.
this need to be addressed.
burst concept is acceptable but it need to follow global rule. GCD.
2. suggestion
player can't use skill during fly time.
pounce GCD start after landing.
