As an omen main, I can confidently say that, if you aren't Flexinja or you don't have galaxy brain, you should play omen as a support character. Almost like sage where you should aim to die last. If you die, you are likely the only one on your team that has smokes and as we all know, smokes are essential. Don't entry frag with your tp like a duelist. Giving up smokes means that your team has to clear so many more angles and gives them less time to position for post plant. That could be the difference between a round won and a round lost. Aggressive omen plays have their place in Valorant, but remember, you are a smoker before you are a duelist.
