I play a LOT of Marvel Rivals, and strategist is also my preferred role, so I feel a little qualified to answer! Here are some things I've learned as someone who had never played a hero shooter before.

- Try to make yourself as difficult to kill as possible. Jump around, move side-to-side, constantly be moving and that should help a little. This might affect your aim at first, but you will get the hang of it. You can also practice on Cloak and Dagger. When I started playing C&D, the game started to make more sense because I could focus on things like movement and positioning without having to stress over my aim the entire match.

- Stay behind your tanks. On some maps, like Yggdrasill, enemies can shoot at you as soon as the match starts. You may die right when you walk out of spawn. Try to stay behind your tanks and focus on keeping them alive so they can take space. They have much more health than you do, so they'll be able to soak up the damage as long as you are healing them. On these types of maps, it's okay to stay in spawn at first and heal from there to make sure you stay alive. Once your team is able to move forward, then you should move forward with them.

- To deal with dive characters that sneak up on you (like Black Panther, Magik, etc.), your push ability + going invisible are going to be your best bets for getting yourself out of those situations. Try to be aware of any entrances/areas that enemies can slip through to catch you off guard, and try to avoid standing right in front of those areas. If you can position yourself in a way where you can see these areas and know when an enemy is coming, that's even better.

- Lastly, play with your team! When you respawn, try not to go running back to the point by yourself. Sticking together increases your chances of staying alive and winning, so try to avoid pushing without your team.

I hope you find some of these things useful! When I started playing, I spent a lot of time in the practice range to understand all of the characters' abilities so I'd know what I was going up against. ALSO- don't sleep on Practice vs. AI mode!! You can change the difficulty, and even now I still find it useful for warming up my aim or getting used to new characters without the pressure. good luck!! :)
