When I Bard I roam when my adc is at altar or the enemy has backed
When do you roam? Personally i find it infuriating when a Bard is supporting me and always roaming leaving me to 2v1 and take pressure and zoning from a Twitch/Raka for at least 23 min of a game. Basically not there to zone, to heal to do anything for bot actually. And of course costing turret, and then as an adc you are forced to also try to get bot lane solo without the Bard because he is basically everywhere but with his team or his carry.
It's not like this Bard was warding even, 12 wards in a 40 min game is ridiculous low for a support.
So, if that Bard see's this. You screwed us all.
That is not how to Bard.
