My two faves are notorious for this.

GNB requires you to trigger a skill at the end that doesn't (seem to anyways) go off if you don't manually press it at the end of a long windup animation that you can be interrupted easily in. Its LB is laughably avoidable and pointless in most cases.

SGE not only has to ground target its LB but also has to wait for a cast animation and sometimes server ping devours your 2-3 inputs (depending on if you have to move it) to use it. So most times I'll place it and get ganked and/or silenced before landing it.
