but is on your team :v

I’ve played almost 200 games of Bard, and I have some glaring weaknesses I was hoping people would have some answers to. I’m in Plat 4 and here is my op.gg for context.

As a champ bard is known for his epic roams. But I find myself glued to botlane with the occasional roam to mid probably once a game when I have time in the first 15 minutes. I end up going top around one out of every five games or so. To me this seems to be very low. I have a few theories that I think may be leading to this.

1. I tend to trade very aggressively in early levels. This leads to me needing to base at around the same time as ADC. As a result I have very little time to go anywhere before a wave is crashing.
2. When we do get a crash and I am relatively healthy it feels like before I can get to river my adc is trading with the enemy under tower, regardless of circumstance. Even just getting wards down leaves my adc chuncked, but not backing. I feel responsible for not letting them die, which leads to bad decisions.
3. On the off chance the stars align and I have the ability and time, it is not the correct time to go to a lane. Either they just solo killed or got solo killed. Or drag is coming up. Or any number of reasons that would leave me as the only one in that lane.

I know that I’m missing something here that is leaving me as the victim of my own poor decision making. I’ve tried pinging my intentions, just leaving, and trying to base around timers, but there doesn’t seem to be a clean answer to me. 

How do you decide when it is appropriate to roam and when you need to be a babysitter?

I also realize that my KDA is terrible over the past 30 games. I’ve been intentionally trying to limit test now that I am feeling more mechanically confident. I think I’ve got a grasp and am reigning in the deaths right now.
