Yes , Yoru is one of the best agents in game(haters gonna hate) . Since people can't make good use of the TP and the ulti ,heres some tips for them:

1. FLASH TP : Its nothing new. You put your gatecrash (TP), Flash and then teleport to the other side. But heres what players get it wrong. NEVER LET THE TP STICK TO THE WALL AND THEN FLASH TP! Better to let the TP have an appreciable distance from the wall and then flash TP. This helps you to make the enemy mess up their aim if they try to preaim when they're flashed.

2. Use ur FAKEOUTS : Yes fakeouts are useful especially for the map Bind where you can make outplays witht the two teleporters. Fakeouts are also useful to mask your Gatecrash (by sending both of them in the same direction) as fakeouts are mostly ignored by the enemies.

3. Dont always use Gatecrash aggressivevely: Whether on Attackers or Defenders Side, Gatecrash is a very useful tool to gather info and rotation. Place your TP in a safe place outside the bomb site. If you are unable to capture it, TP back so that you can rotate faster and watch for flanks.

4. Using the ulti:The best way to use the ulti is to gather info and TP back to rejoin with your team . If you are able to pick one or 2 kills , dont be greedy! Its better to play alongside your team rather than dying alone.

5. Try to make lineups for the flashes: If your playing in higher ranks, its easier for the enemy to dodge your flashes. Hence try to make lineups for the flashes which are always unexpected by the enemies .

6. Learn from the pros: Ethos and Redami on Twitch. For those who want to see situational gameplay for Yoru.

7.Have fun : Yoru isnt a bad agent to play with. You can be really good with any agent only if you know how to play with him/her. Try experimenting but dont overcommit. Have fun and keep flashing !
