Playing out of control requires a lot of good reads and snap judgements, but hopefully I successfully highlighted some ways you can bring the game back. Analysing demo's of games you have played will help dramatically in seeing where you lost control or won it back. Looking at that will build your understanding and skill as a player, so if you ever came across a situation you didn't understand, check the demo and all POV's!
But yeah, here are some notes:
1. As a boomsticker, pressure and attack spawning weapons (try to see if RA is open/steal-able off of your spawn as well). 2. Support team weapons, don't wait around for 20seconds whilst a weapon is spawning. 3. Use ambushes well 4. Try to stop the enemy team from setting up on YA, because after that it can get bad. 5. Your team can make good use of flooding to finish off weak enemy weapons who are trying to hold YA. 6. Check my other video from my POV (tks vs 666) about decision making to see how I make decisions off of each spawn, although we are often in control in that game, it will give you insight into my priorities.
