Hello,
I really does not like to have a unit which has 10.000hp and can be instantly repaired 2-3 times in a row... I dont see a benefit for that in the game. What I see is people exposing their Dreadnoughts and have not to pay for that mistake. The instant repair is game breaking in my opinion. Combined with regeneration it is not nice to watch.
Its bad in both ways: I dont like to click the button to repair it (because sometimes it does not work) and I dont like to nuke it and than be pissed-off 2-3 times in a row while losing units.
Plz think about this its not fun to play with such a mechanic. Plz simply get rid of it. Maybe introduce a orbital heal skill but it is far from being balanced (I remember a game having two SUB Dreads in a PHC Base with the PHC is not able to kill them with much more forces).
My solution [Update1]:
-I would prefer a heal for costs of quanta like regrow in WOW (burst heal and heal over time) with a couldown long enough to be not abused. (Maybe we have a circle to cast it. Within the circle the dread with the lowest hp will be healed (maybe drones searching the right dread(maybe named emergency drones)) in order to reduce precise clicking -> the ammount of clicking is 3 instead of 2 (what I say vs current system))
-Otherwise making them invulnerable for a period of time with heal over a period of time could help (in the same circle way).
(maybe u can use one for sub and one for phc (invulnerbility for phc and and heal for sub would make the most sense if you consider healing after fights but maybe not so much gamewise -> if we consider invulnerbility for sub maybe the name could be shield overload (maybe reloads shields over time and makes them invulnerable for a period of time)
I think its more predictable if you know that your opponent can only use it one time because of the long cooldown. I think this could be overall a nice improvement to get rid of "I cant click" and it "heals the third time" and you have a "new ability" and maybe a "new building" for advertising and now "you can scout if you opponent has the ability ready" and they are "slightly different" by "nearly the same effect" (what people want).
[Update2]:
Plz get rid of neutral AA we have less possibilites in the gameplay with it.
[Update3]:
Plz consider the mechanic of the opening.
See you
