Taken down easily by pilots? I disagree. You could destroy a Titan by getting on his back just once in the first game if you had a shotgun. In TF2, you have to first take out the battery, then rodeo the Titan a 2nd time before you can drop a grenade into the battery slot. I have no issue with this, but it felt easier in the first to me. Also, Scorches flame shield instantly kills enemy pilots that get too close to him. Just point it upwards and it'll kill an enemy on your back.
