They [Blizzard] did say that the placements will resume as normal once the beta season ends. So hopefully, that should weed out people who are unable to adapt to the situation of the new competitive mode as fast as the others.
Role queue essentially saved the game from being terrible for majority of the time. No longer you have to concern yourself with lack of healers and tanks because everyone instant lock onto DPS for majority of the game and maybe switch when they get their shit pushed in.
Sigma is pretty damn interesting to say nevertheless, maybe a little hard to managed. Though, I haven't had the chance to use him since everyone in competitive is so ready to use him straight out the gate without much practice... lol
The only issue I have with the new format is the DPS and Healers. Healers because you have some that play them as DPS rather than healing. I can't tell how many games where the healers outright refused to do some healing because they want to get those kills. Thankfully, with the new system in the works, healers that can't do their job will take a huge hit in their rankings, and you'll rarely see them in your rank as an result.
I got plat in all three roles and honestly, I pretty much don't want to go back to the old system. Some might complains about the lack of flexiblity to switch onto counters because you have some people that are just use to playing a single hero, but I feel that'll improved over time. DPS will now have the responsibility of actually playing the game with their teammates, rather than bone-rushing in.
Brigette... I'm on the fence. I seen a few Bridgette in comp and when she shines, she shines like a diamond. But when she doesn't.. it gets pretty rough for her. I feel like they should give her 500 HP shield back? Kind of ridiculous that McCree can break through it with fan the hammer, lol.
