Most irritating legends?

I don't mean in regard to how your teammates use them, nor their aesthetic or personalities. 

I'm talking being in opposition, their abilities that frustrate and irritate you and stand out the most when it comes to affecting your game play?

For me;

Fuse - that bloody popcorn maker tactical

Bangalore - that missile drop

Caustic - his gasses

All above very good for; dispersing enemies, reducing shields, finishing off after shields, or eliminating downed opponents.

Next down the list would be;

Conduit - Jammers. When they work, they are mega annoying. But I rarely see them and rarely see them cause bother.

Pathfinder - swingers. People who swing well can be annoying.

Vantage - that rifle. That 2nd hit really makes you go into hiding. But I usually outvantage a vantage, or otherwise don't receive it too much. (Personally I get a lot of shield breaks, knocks and eliminations using it)

Ash - snare. Only one time did it cause me any bother, someone expectedly used it and followed up with an arc star. Otherwise no issue.

I feel like Catalyst's ULT could be really useful when you have enemies fighting at the edge of a ring near a new mid round stage; could force them through or around it likely getting finished off by ring or easy pickings. But not seen too much.

I've been trying to think about this in influencing my legend choice,

(had a couple good goes with Fuse. But not really worked out for me. Trying Ash now.)

How about you? Any irritants out there?
