Caustic is terrible, and the new map shows it

As a Caustic main (currently) I have noticed that the traps are getting triggered more and more whenever I place them inside a door, sometimes without any enemies around, like if I throw it too close to a door.

I feel like this was a hidden change they implemented at the last part of season 2 and it is definitely frustrating when you are trying to secure an area. A good fix would be more doors to not trigger the traps.

Also, since this map is more open all of his abilities are becoming a lot less useful. I love Caustic in small circle scenarios and close quarters, but there is a lot less of that with this new map. So I also agree that the range should be increased for all of his abilities, especially his ultimate, in order to make him more worthwhile in this new season and map.
