What do you think of this Malphite build?

QSS is really out of place on Malphite. If you need to remove CC or have some MR just get . QSS is for squishies that need to remove CC instantly to survive but as a tank you can normally just survive any CC. I assume the was going to be a which isn't that bad on Malphite if you are looking for that 1 offensive item to build after being tanked up. Aegis is a great item to build for your team but I notice the enemy had very little magic damage and you probably didn't need it.

However, It looks like you were a support Malphite. You needed to buy . Starting with a would have been ideal and building it to would have also been a great item as you could shield your allies for a good amount. All in all, you built a top lane Malphite (with a pretty useless QSS) and you are lucky you made it to the late game.
