Going E level 2?

Just something I've been thinking about lately. Are there arguments for going E level 2 rather than W (I assume most people go W level 2)? For example I've found it to be really helpful if me and my adc are winning the level 1 2v2 and having E just helps us chase them down to secure a first blood.. but in other situations I wonder if the tradeoff of not having heal and shield in the 2v2 could make the level 2 E useless. Curious to read perspectives based on matchups/etc. too. TYIA!
