The shield scales better without maxing it first, it scales with your max heath which will be getting increased by the W and the detonation scales with their max health. So it's better to leave that at one point until later where you would have enough health to make increasing it more efficient..

It also has a huge mana cost, can't be used nearly as much as the other 2 abilities and is a lot less reliable. So it's not first max material.
