Hourglass and Kaleidoscope maps are impossible in breakthrough attacking

these maps are impossible to win in breakthrough as attacker (in pvp), because the entire enemy team is cramped up on 2 roof tops that are right next to each other and the ONLY way to get there is through the elevators or heli.
but helis cannot get there because the rooftop are infested with hovercrafts and AA soldiers. 
AND FOR SOME REASON YOU REMOVED THE ABILITY TO SPAWN ON TRANSPORT HELIS THAT ARE HOVERING HIGH ABOVE?!? which was a core use of the transport heli IN LARGE MAPS IN PREVIOUS GAMES.
it won't matter if you TRIPLE the amount of tickets the sector of capturing skyscraper rooftops is a complete waste of time, de-moralizing and a serious flaw in design to a point it seems the developers have not played a single MATCH of breakthrough in these maps.
what's worse is these Objectives are on one of  the tallest buildings in the vicinity so there are very very small amount of areas to parachute from.. 


my personal suggestions for All Out Warfare Breakthrough would be:

first of all, make breakthrough more dynamic in general. for example; first sector - defending team has no access to heavy vehicles. etc etc.. 

2nd idea, change the sector with rooftop objectives and place the objectives elsewhere. 

3rd idea, just the sectors with rooftop objectives, disable the ability for the defenders to para any vehicle on the top part of the skyscraper.  AT LEAST IN BREAKTHROUGH ONLY

4th idea, just try to think of something,  so the attackers have anything but the elevators to get to the top of the building!
