@ Sithlord
First things first, i'm very clear on your position.
One relatively low cost military tech to get a larger long term advent capital fleet would greatly help the advent loyalists.
The advent loyalists would still have to earn the cash to get more capitals, 25% capital ship cost reduction is still going to be a serious investment.
Idea #1 allows for advent loyalists to better deal with capital ship losses and encourage them to have a larger capital fleet. This ensures a stronger mid game advent loyalist capital fleet, and ensures that even with some losses the advent fleet will be able to recover their capital ships to maintain fleet viability.
Idea #2 allows for a stronger advent offensive right off the bat, the most OP idea of the bunch. This ensures a strong Early game advent loyalist capital fleet, that the loyalists would use to gain the tactical advantage and have more power to gain the upper hand in early game territory acquisition and skirmishes.
Idea #3 allows for cheaper capital crews so that the advent can field a second/third/fourth+ capitals much easier then the other races while keeping the same attrition costs. This ensures a strong advent loyalist mid-late game capital ship fleet because new capital ship crew training costs are the biggest barrier to having a large endgame capital fleet.
I'm torn between idea #1 and idea #3.
I would greatly like to see your reasoning behind why my method of implimentation is flawed.
You want to approach the problem directly, and buff advent capital durability when in fact there is no need for a direct buff. The problem with this is how this will greatly change other fundamental aspects of the game. Capital ship cost is easy to balance.
Changing combat values is NOT easy to balance.
Changing the advent loyalist capital ship durability would do nothing to really help the advent loyalist faction, and they already have had their capital ship durability buffed. They were buffed by having loyalist culture reduce the efficacy of the vasari phase missile shield penetration capability. So, as long as the advent loyalists have cultural influence on vasari worlds they attack, their capitals will hopefully have enough durability to withstand a vasari opponent long enough to make a difference.
Also, the developers have shown a strong desire to make economic balance fixes to the game(time efficient and effective). The main two changes to the Titans and the Corvettes have been with increasing titan and corvette production costs.
Instead of considering lower advent capital durability as the problem, you should accept that advent capitals are weak, and that is okay because since they are weak, they can be buffed to ensure that they are more numerous. This would maintain balance, because one advent capital by itself is relatively weak.
This plays well with advent racial synergistic capital ship abilities. Also, advent capitals would be far more resilient against the vasari phase missile assault considering they get more phase missile blocking inside their own culture.
The rebels are unique in that they have a super powered titan. The Advent rebels are like the "sith lords" of their race in star wars, they have their strong individual, while the advent loyalists are the "jedi" because they use the group synergy to overcome their opponent. The loyalists hold true to the old advent military philosophy that synergy is king, while the rebels hold to the military philosophy that bigger, badder, is better. Please note that i'm using the term "military philosophy", this isn't a made up idea, this philosophy is actually how the two factions play, or should play.
The Advent Loyalists suddenly start to make sense as a whole faction, and their endgame support titan suddenly becomes less gimped, because the loyalists don't necessarily HAVE to have their titan to win anymore.
This would mean that the Coronata really doesn't need to be improved a great deal (its abilities still are rather gimped at the moment though). The powerhouse of the Advent loyalist fleet is in its Capital ships. This also follows well with reaching tech level 8 advent military, and researching that ever so lovely experience buff/gain for all capital ships.
All of a sudden the Advent loyalists have a viable, balanced endgame strategy as well.
The ideas I presented above are all different ways to solve the problem. After all, i'm trying to provide a range of ideas to give the developers a wider range of options to choose from, if they deem any of these ideas worth looking into.
