youtube: League of legends - when 2 of 3 actual Zyra-Bugs meet her ultimate
The plants spawned/faced in direction of the last aim, Jax. As Sion was "behind" the directon of the plant and in range of the plants they will not recognize him (wich is the first bug). So the plants decided to shoot further in direction of the (then dead) Jax corp (2nd bug) instead of focus the Sion behind wich was between plants and tower.
Every match is a sad gameplay. Worst is Zyra support actually. You cant set plants behind the vs minions to zone out because they face half of the time in the other direction and don´t shoot - can be easily shot down from the other (vs) side.
Riot.... well. Perhaps at least 1 person in your company should do something with this game instead of struggeling if someone is women/man or something else.
And - more "content" out of 1 match within 3 minutes 2 ultimates: https://youtu.be/OeZwMMz2n9U
