What role is best to learn for a past Dota 2 support main at 4.2k solo mmr?

I have spent a bit of time playing the role as AD carry, I chose this only since I have the ability to farm and have a decent CS when the lane phase ends so I didn't have to spend time farming when my team needed me. These are champions that have seemed to fit my playstyle and ideal positioning as an adc during team fights.

With that said I have found that more than a few games have gotten out of control before I could become a factor for my team, so I was wondering what other lane would possibly be good for a higher elo support main from dota 2. This season after placements I only got placed in silver 4 which to me was disappointing (after playing league 2 months). After placements I wanted to feel like I had a good grasp on how to carry and develop a higher win rate before returning to ranked play.

After a while of losing games both by my fault and others I got discouraged and returned to Dota 2, played that for 5 months and now I am back. The reason for returning is since the Dota 2 community or the mmr I was playing at was extremely toxic, long que times and just not fun anymore.

Now that I'm back I wanted to try something new, find the role that fits me best.

These are champions that I have found fit my play style and have found success and ease playing so I was wondering if anyone could hel me find the role I should be in so I can play better and enjoy the game more

If you got to here, thanks for taking the time to read my long post.

All advice is welcome and appreciated.

Thanks!
