if i'm to decide. I prefer pairing range and melee type heroes. sven - kardel mirana - centaur or vice versa it really doesn't matter where lane they are, as long as both heroes support each other and that's fine. range type is suitable for support so pairing it w/ melee is not a bad idea. before that your team must decide a hero as your ace (The one who will not join GB and focus on farming). sniper or jahrakal is fine. they can be unstoppable later round. BTW hero at mid should be range-type. you know what i mean. Fog war is annoying and range-type only has advantage on that area.
