yeah, it's just a little bit silly tbh, there's nothing you can do to counter either of them
literally the skill involved with nudge is:
hold your attack until you are facehugging a shielder, press V, free hit
wrinse and repeat
in what possible way is this a fun or skill based mechanic ?
the same thing applies for HX
run away spamming shots as long as you can, if you see an archer run away, other than that there's nothing infantry can do to hurt you at all.
Shoot, stay just out of an infantry's range, wrinse and repeat until you hit him enough times to kill him. You literally have no predators as HX.
