Clearly SE is okay with the toxicity.
SE had this ingenious idea to add a rating system with horrible point gain/loss issues to a small pvp community. Originally it wasn't even possible for Gold+ to get unranked players, now the matchmaking just stacks multiple unranks with Gold+ for "balanced" teams (although

Losing 20 or more rating because SE thought it was intelligent to balance teams by throwing unranked healers on your team while the unranked themselves goes unscathed from the rating loss. The devs are just begging for toxicity among there players, and the only made it worse since season one.
Now that is off my chest, SE desperately needs an unranked 4v4 mode and force players to
WIN a certain amount of matches before being allowed into rank.
