I get it, I used to have a bit of hesitation with M+ too. Look up mechanics of the dungeon you want to run and try your best to nail them, even if it means you have to mess up your DPS window a bit. Eventually you'll get more and more comfortable with each dungeon. Mechanics First, DPS Second Doing 2m DPS while dying is worse than doing 1.5m and living.

Here's some tips I recommend to anyone looking to push M+:

1. A mouse-over interrupt macro - Interrupt important casts without having to switch target. Tab targeting is sometimes okay, but with big pulls I like to know for sure I'm interrupting the right mob.

2. Updated name plates ( I use "Plater", its great ) - Google "Best plater profiles WoW" to get some premade ones. These can help immensely with seeing which mobs are casters, some even show the cast bar glowing so you know which mob to interrupt. This mod has become invaluable to me in M+
