Mythic+ seemed like something incredibly complicated to me. The timer, coordination, mechanics - all this was scary. But as soon as I started reading the guides on DPS Tier List in guide everything fell into place. I understood which classes to take, how to go through certain rooms, which affixes affect the fight. Now I calmly go through +15 keys and even help others. Without this site, I would never have dared to go beyond the regular dungeons.
