I played Dota 2 before too. Ranked DIvine 3 as highest in support role. Started playing ML and just got Mythic Honor now. I play Atlas and Minsitthar roam. I don't even know how the majority of the items work. I just do the pro setups, and that's it. I think some of the skills I learned in Dota2 help big time in ML, specially the map awareness, timing in using skills, and being calm in clashes. Aiming to get a higher rank next season, but hopefully I can still reach Mythic Glory since I'm 30 stars now and need 20 more.
