Right, sit down and shut up.
Ignore the fact that SG have just published their entire 2019 development schedule, because this is the best idea since someone decided that meat tasted better cooked.
Now I like war bonus, but I know that’s not universal.
And alliances like killing titans and winning wars.
SO LET’S COMBINE THE TWO
Every time your alliance defeats a Titan, you have a x% chance of capturing it.
These are kept under lock and key until the next war.
Then the leaders can select their titan of choice.
During the war, same drill, war bonus bar fills up and then
BOOM - TITAN STRIKE - death from above, fire and brimstone (or ice, or the weird, glowing purple balls)
It’ll need some balancing, the hits would be much softer than the titan battle, but proportional to the level, and some starting stock.
Thanks to @annieb for the inspiration
