Suggesting things which are not feasible to implement doesn't move us forward.
Welp, you keep making bad assumptions (see below).
The problem with Sector assault is that it's the only loiter plane with a bombing run assigned to it (which i can think off at the moment). Issues which i addressed before.
Any offmap which a big enough AoE can and will hit inside enemy base, specially when the base space if too close to a point or the base been really small.
Edit: just tested it, and you can easily hit south spawn on Langreskaya with Air supremacy.
It will get nerfed. The thing is to understand what and why it's happening and how to change it.
Because for all that it matters, the old Air suppremacy was an "artillery" attack. Bombing attack on new Air supremacy doesn't lock down targets, it bombs a predefine space based on map layout.
First of all, I am not the dev of the game, and there is no way for me to make a judgement of what is feasible or not for change. To attack me and accusing me of making assumptions when I am just reporting what I see in the game does not make for a constructive discussion.
I agree that my suggestion for UI changes was not well thought through, because frankly speaking, my intention was only to suggest that the UI needs to match the mechanics at work, which it does not from a player's QOL perspective.
Even if the UI does give the information, it is not given in a way that can easily be deciphered for players because it does not follow the conventions set by how other abilities behave.
This brings me again to Air Supremacy. First of all, I know for a fact that this ability used to be able to drop bombs in enemy base due to it's large AOE, and I have used it for purpose as a brit player before. As far as I know, this no longer works since one of the patches pre GCS2. Maybe something has changed again due to the latest patch. I'd love to see a video of your test result. For clarity sake, I am not talking about bombs dropped on the edge of the base area if that is what you are referring to, as before you were able to cast this ability just outside the area and obliterate half of the base. This behavior, as well as other abilities like Concentration Barrage that allowed you to fire into base, were all considered to be broken and detrimental to QOL so they were all changed in one of the patches. This is not an assumption, but observation based on the games I played. I don't believe you have any reason to deceive so I will test this once I get back.
The reason why I want to use Air supremacy as an example is because similar to sector assault, this is a highly potent ability with the potential to wipe the whole army with a single click (again something that is considered to be detrimental to competitive play by both balance team and the community). The reason why I don't have a problem with this is because the UI clearly indicates where the danger area is, and clearly indicates when the player is safe from the bombing run. The AOE of the bombing run is clearly defined (scatter around the edge of the circle is not big enough to be problematic), and the circle lasts until the bombing run occurs, and then disappears. Additionally, there is 0% of a bombing run happening after the circle disappears. To put it simply, a player can simply leave the circle, wait until explosion happens, and come back into the circle to avoid it.
Sector Assault's UI can not be interpreted like this due to the tracking mechanic, and the undefined nature of when the bombing run actually occurs, and where it occurs. Not only does the bombing have the potential to occur anywhere on the map, it can happen even AFTER the circle has disappeared. The way this ability requires the player to interpret UI information in a completely different manner to other abilities is confusing and detrimental to the game.
With that said, I can give a new change proposal because it is clear you are more concerned about semantics rather than intent.
This ability needs clear indication of when the tracking phase starts and ends, and it needs to clearly indicate where the danger area is when the bombing run occurs. This can be done by:
1) Change the ability so that it is applied to a map sector (as the name suggests), so that during the tracking phase, the affected sector is highlighted on the minimap, and units within the sector is subject to tracking. AOE circle is not displayed here.
2) If a unit was tracked, and a bombing run is initiated, the destination of the bombing run is marked via an AOE circle indicator before the bomb is dropped. With this change, as OP as the locked on nature of the bombing run is, this makes it manageable.
Again, I don't know if this is feasible or not because I am not the dev, but I am not suggesting addition of any mechanic that is not already in the game, so based on the information I have, it seems possible.
Lastly, the kind of attitude shown by the vets here makes it pretty clear why people are reluctant to give feedback. I understand there is a problem with people who don't understand the game participating in balance discussions, but to expect people to know information they have no way of obtaining aside from being involved working with the devs is not how to encourage constructive discussion. This is a sure-fire way to drive away even qualified people from contributing.
