Climbing with galio

geniune question. how do you guys do it? i started playing galio end of last season into this season and i love him. good damage, rotations and bulkiness needed to be a great followup engager. that being said, i just cant win with him. i finish games with positive kda from all the kills and assists but i dont feel my teams are not carrying with the lead im giving them. i admit that sometimes im overzealous with my follow ups but its nothing xompared to what i bring to the table. im think of switch back to akali/ aurelion who have higher agency while being just as impactful in team fights. so again i ask, how do you guys do it?
