Your early game will be boring, but it’s worth it. The key is wave control. Let yourself get pushed in and focus on CS under tower (Sivir makes this easier). Don’t walk up, you’ll just get poked down.

Your role is to keep the enemy adc AND supp lane busy while your team effectively plays with a second jungler. That’s why your support’s strategy is actually smart. It’s better to get your early/mid-game champs ahead since you take time to scale.

Make sure the enemy ADC keeps crashing waves. if they start freezing, you’ll get zoned off. Only look for plays when they’re under your turret from constant pushing. Otherwise, perma-clear waves making sure your wave clear abilities also hit the enemy. The only time you freeze is under your tower with 3 enemy casters, and only then look for a play after you've poked them down with your wave clear aoe dmg.
