Link to the tweet is here:
Further down someone asks:
"arms and active instantly"? Does that mean it can be fired at a person directly to be trapped? No luncher"
"No, it has to be placed and has a travel time."
Thoughts on this? This essentially makes trapping become an actual skillshot, subject to latency issues and whatnot. I think it will be really really difficult to land traps on moving players in WoD unless they increase the travel time to near instantaneous.
Also the loss of scatter shot for peels and interrupting will be huge.
