Guild Wars 2

I noticed that the Mortar is too short.In WvW you mostly cant reach the ground from the Walls from the castles.Also they run faster that you build the mortat somewhere.But the mortar has nice features and to make the elite makes sence i think the range should be about 1700 to 2000 Range or something.So why i should use the elite mortar if i can buy a great mortar with wide range at the shop.I like the mortar, but at the moment the mortar make not really sence at the moment.
What you think ?

grenades beat mortar in every way, except a knockback and a heal.
But than you can’t use the knockback or the heal where you most need it: at minimum range!
