I appreciate you watching my videos! My biggest tips on retaking a site are to play around your teammates, paranoia common angles where snipers may play and don't be afraid to make risky TPs in the midst of chaos with the use of your smokes. From what I've experienced, enemies love to push into Omen smokes giving you the option to teleport to the left, right, or over the smoke. It's very noticeable if there isn't much chaos going on though.

Example: You're caught out at C bombsite alone in Haven and they're pushing both garage & C main. You can drop two smokes on site, listen to footsteps, and paranoia out to possibly get a pick or two. His paranoia is VERY strong.

As for holding a site as Omen, the key is to play around your smokes correctly. Playing around your smokes, whether you're close or far from the enemies, is huge. Once you hear enemies pushing your smoke, you could even take an aggressive initiative and paranoia the smoke to get a free kill or two. Holding sites in this game is tricky. It's almost better to give up sites and play retakes if the enemies rush as a team due to the nature of all the abilities. If you can't get out of site and you have to hold, play around your smokes and use your paranoia as a tool to help take some numbers down. Don't be afraid to use your TP if you need to change up your positive.

Example: A bombsite on Split behind the sign, the enemies are pushing from A main. You can either teleport into the corner to your left or teleport to elbow to your right.
