The change does not bring the 2 abilities in line for a number of reasons:
1) S.D.Z requires control of a sector with resources you want to get ,to be used, A.S.D does not require control of any territory and resource land in his base.
2) S.D.Z. requires around 1 minute and 5 passes to be used, A.S.D is used in one.
3)S.D.Z is MP to fuel or MU A.S.D is MU to fuel.
In a 4vs4 game a simple FU cashes will return the same FU just over 4 min instead of 1minute and will be a become a better investment after that without taking an ability slot.
4)In S.D.Z the player has no control over enter or destination (since it has to be sector), while A.S.D the player has some control over flight path since he can control drop the point within is base sector.
...and never receive free AA in the version of base defenses...
If you think this is bad try using Allied supply drop in any game above 2v2.
Base AA where nerfed and are far worse at shooting down planes, even in 4 okw map the plane will manage to pass the base AA more times than not.
I actually have used A.S.D. more times than S.D.Z and it contributed significantly in recent 4vs4 game by me feeding UKF players with fuel while my plane was shot down only 1 out of around 5 times used.
So now take your new drop and compare it to,...
Often the drop has an extremely high success rate as you force your opponent to react immediately. ....
I have compared them, have you?
In S.D.Z. one has around 1 minute to react in ASD a few second...and even if one does not react in the 1 minute he can see the flight path the be prepared for the next one since one can not change the drop site...
If one wanted to bring the abilities in line should allow S.D.Z. some control over flight path should be done 1 pass and there should be some sort of ground counter A.S.D.
As it currently stands A.S.D. is better ability
