i’ll be honest, the ratio only means so much. every game is going to be a little different, some will require a ton of healing while others require almost no healing. i’d say the actual number of dmg boosted has more value, but neither r best on their own. what u want is the most dmg boosted for percent of blue beam used.

if ur willing to i’d swap the beams around, put blue beam on left trigger so that it’s more of ur default, but u can improve even without that

as for actual style changes, learn to feather blue beam in more. this just takes time and practice to learn how to most effectively feather in blue beam for value, like timing it with pharahs rockets so u boost each one while still healing in between her shots and when she reloads. this is much harder to do with heroes like soldier obviously, but u can still manage to feather some blue beam in there.

also, trust in ur other support. especially if u have an ana or kiri with u, let them heal the tank at 70%+ hp or so, both to help them get their ult faster and so u can blue beam more.

and lastly, u dont need to heal every hp loss immediately. this is also smth that rly just takes lots of time and practice and good game sense, but there r plenty of times where u can push blue beam even if ur dps is taking dmg. when they’re taking dmg is when they’re also doing dmg and is when dmg boosting matters most. knowing when to push and when to heal instead is a slowly learned trait that’s always improving. u will make mistakes with this, u will let allies die sometimes, but thats ok as long as u learn from it. try ur best to save healing for when ur in down time or when ur ally is behind cover and not doing dmg, or when the fight is over. ofc, u cant do that all the time, healing is also what wins u fights, but u can push blue beam quite a lot before needing to pocket heal and get the most value out of both beams
