I really want to like aram

i've been playing for over half a year. I played aram. about 8 or 9 times. And it seems like am getting random champs. renekton. tryndamere. literally shit tier aram champs. while am always getting matched with some ranged harass champion. kayle sona ashe. its really stupid. I really want to like this mode but it always seems like am at a disadvantage at champion select. it just doesn't seem random at all getting against the same champions over and over again
