When playing support brand or really any support I like to use my presence and zone the other teams ADC and support this way they have a harder time trying to CS. Brand is perfect for this because by starting W you are able to do CC and with his W range you can zone the enemy out easier in the lower elo's. I like to go Q next so I am able to stun the enemy ADC or Support preferably the ADC so we can get kills early on. Now when it comes to getting kills I prefer that my ADC get them instead of the support but the thing with brand is that when your ADC is not having a good start then it's okay to take one or two kill, try not to because the goal of playing support is to aid your ADC and your team later on so your job it to give them vision so that they are able to react faster to being ganked by the enemy jungler. The second job is to give them chance to get kills and get your ADC fed so they can pop off. The third job is to watch the map and have an idea of where the enemy's might be like taking objectives on ganking or just where jungle is in general.
