If there's one thing I could ask for in this update - other than the awesome updates you already outlined it would be a fix to Imperial Elections during League Wars. I recently played a game where i was the commonwealth(catholic) with 2 protestant elector allies. They absolutely loved me and voted for me in lieu of Austria(unbeknownst to me) swapping me to the catholic league and breaking our alliances and becoming hostile. I fought tooth and nail to kill my king (who wouldn't die at the age of 76, it was very scary since it was a good 50 yrs in and a very protestant-heavy league) by sending out one stacks. After i died, i immediately left the catholic league and reestablished trust with my allies (which had fallen from utterly to somewhat) at which point they wanted to vote for me again. If anything protestant electors should vote for a very weak catholic country so they have a better chance of winning the wars.
