Yep, PVP in general is garbage. People who take too long to make turns and just as many with bad connections. KC Cup is the only PVP event I tolerate. The others can disappear!
The same has happened to me hundreds of time,
Duel begins>opp doesn't move>low internet icon appears on their side>when the timer gets to around 50 they finally move>they normal summon rosemary set 3 and end turn
