The leaver penalty is only activated in ranked right? Say you play normal queue and leave, you won't get penalty. But if you play ranked and leave then you get penalty (time out) for all queue mode right?
Leaver penalty in ranked is fine since it's about ranking / ladder. But don't put leaver penalty for normal queue. Normal queue is really cancerous, nub teammates, and I mean it * really nub, no skill but still hot dropping, no communication, no ping, doesn't use ability at all, it's like playing with a baby or baby sitting, nobody likes to baby sit.
To be honest I think leaver penalty is stupid until you can fix hacker problem to 90% free of hacking and fix forced solo / duo squad bug.
You want me to sit down and to be forced to play against hacker and if I leave I get penalty? what * is this?
