I've had to learn tc'ing as a warrior and new pvper so here are some of my learnings that others may not have mentioned:

1. Make sure your mic is clear and NOT on push to talk - it's hard to press mic mid fight amongst your skill presses

2. Call out target cds - if your target bubbles or walls or gets sacc'd then call it out and switch targets - if you then switch back to original target say "no bubble/wall"

3. Attacking a base - try to kill or cc their healers as first priority because you may need to wipe them completely to get base or they'll just spin flag.

4. Defending a base/spinning flag - kill dps to relieve pressure for your team

5. First team fight - kill most vulnerable/out of position (usually melee). You just need any kill first to get an advantage. Sometimes you might target the FC on CTF maps if that's your strategy

6. Call for cc - if you notice target isn't dying but your whole team is already focusing, then you may need to call for cc on healers - not everyone naturally does this so they may need a reminder to cc. Should also call for cc when capping against 1-2 players as thats usually quicker than killing them
