For what it’s worth anyway.
I’m not the most experienced player by any means - but thought I’d just give my 2 cents and share my experiences today.
TLDR: gotta start at the bottom and network/actively try to make Bnet friends with tanks and healers.
I just started m+ today as a healer. As in, I’ve never done mythic+ or even mythic dungeons before. Last season doesn’t count because I bought KSM last season.
This season I figure I’ll try to earn it legit.
Did a normal, couple of heroics to warm up on this alt, then did a m0. I knew how to heal already from leveling the toon as a healer in dungeons.
I was lucky to meet a good tank in that m0 and at the end of the run, I asked him if I could add him for m+ dungeons. He became my first dungeon friend. Today we did 5 m+ dungeons and plan to do more later. We timed all 5.
Having a good healer and tank in the group really makes a difference. We pugged the other 3 DPS and had 1 group with some real baddies, but still managed to time it barely. Felt pretty awesome.
As a beginner to mythic dungeons, it was also useful that this tank was helping me learn the fights and mechanics as we went along in Discord.
Why am I telling you all of this?
Because the sad reality is that, as a DPS, you will have a much harder and slower time to get groups.
If you insist on being DPS, then if you want faster and better runs, then the first objective is to make friends with some good healers and tanks.
Based on my experience today, I suggest running some m0s on your DPS alt and actively add the people who are decent, especially tanks and healers. Queue with them for more dungeons. Profit.
Oh, and before today, I didn’t even consider myself a social player. In fact, I didn’t even talk to the tank in Discord (though I wanted to after a while but my mic wasn’t working, that’s another story). Just through text.
But I think, if you’re a good player, better players will be willing to mentor you/teach you and keep playing more dungeons with you. Yes, this includes tanks and healers. Since they are in short supply, you need to take the first step and add those people to your list of friends.
Have you DPS players tried these tips already? Let me know here. I have DPS alts of my own that I might want to take through M+.
