So you assume that I will do this? And then can actually predict what I will say? No I won't challenge you on every single details of your gameplay, I just want to call out people that are imposters on this forum, have no idea what they are talking about, and just try to pretend like they know everything. I'm not saying you are, i'm just saying that's why I post these things.
I understand why you would assume this though, it makes sense. People here seem to be a bit toxic at times.
Also, you not linking your armory link or your character is the same as linking it, it proves your credentials and your credibility on what you are talking about. It's easy to talk and say things, but when it's time to show up, that's where you know who's who. Anyone with those credentials (For real), doesn't hesitate to show it from my experience, because it can only be beneficial for them.
Also you calling me "Mr New Account", proves how defensive you feel about this topic. Trying to undermine what I'm saying because somehow I made my account recently on MMo-Champion? So for you it's valuable to have spent a lot of time here somehow?
So, to conclude, no Armory Link in the end, fake screenshot that could be coming from anywhere, defensive about linking your character and actually backing up anything you say ?
That's too bad..
If you don't like to queue as healers don't queues as healers, maybe it's just not meant for you. There was someone who suggested you should go back to DPS, that would be my call as well if I were you.
Leavers increase are increasing because there is an exploit that can be done to increase rating with hidden MMR and numbers of round won. (If you didn't know already). Queues are getting longer for a multitudes of reasons, but the ones your brought up are most likely very minimal. I have friends who play healers and have explained to me their solo Q experience as a healer, and it's really not for beginners at all.
Problem is likely your gameplay, and from this very short experience discussing with you, your attitude (and mindset).
If you want to get better at it analyze your gameplay, record yourself play, watch what you could have done differently, instead of blaming the game and ranting here. Just my 2 cent. You'll see much better result that way.
Good luck!
