You are hilarious. dunno if they can 1shot or no, i was watching Sindrenner one hour ago and he had a deadeye in the match, S/d and rifle, altought he doesnt have the mobility of S/d SB , was really hard to take him down and had a nice damage plus a nice amount of stealth , S#2 is focking good for mobility, enter hit , back in invis (not due to the skill itself) , use rifle , GG, dunno about OP or not, but seems viable in the current meta.
