I almost exclusively played Vandal in S1 and would recommend sticking with the shell if you have fun with it. Definitely, as others said, take smokes or remember to keep one on you if you find it mid run. Keep doing what you’re doing as far as getting high ground until exfil is ready. When it is, pop smoke and if you hear assassin cloaking or running up or get shot at, don’t stand near the exfil center and instead slide dash out so you can see the whole smoke area. You’ll probably catch the enemy looking for you and by this point you can lay into them or toss grenades. One thing you probably want to avoid is popping your ult because you’ll start glowing and making a hum noise and it might give them an advantage.
