I'm down on my hands and knees begging someone to change the .exe to enable multiple brigades for land units and converting land units from one type to another. If I knew how I would do it myself but I don't.
I'm down on my hands and knees begging for sometime to change/fix...
* paratrooper combat
* how the AI handles combat - preferably allowing more soft-coded edits to be done
* unit trading
* the over-powered effect the capital has on the ESE of the entire army
* the create supply dump feature (currently it tries to ship directly from the capital to the place you want to create the supply dump - i.e. as the UK, you want to create a supply dump in Singapore but cannot as the feature tries to ship the resources from London -> Singapore, rather then from a sea province, i.e. Plymouth -> Singapore, so it invariably does not work for the UK)
* ships being able to move port-to-port - perhaps justifiable for destroyers, but for carriers/battleships/loaded transports it gets ridiculous - DH has prevented it so should AoD!
* unit stealing (i.e. EXPing a nation's army just before it is to be annexed - if people talk of Free French units and such, that's what events are for!)
* being able to join an alliance that's at war, while you cannot declare war on the nation they're at war with (i.e. primarily for USA, where it can ally with the UK that's at war with Germany, but typically cannot declare war on Germany in the first place)
* bombing at midnight means provinces can't be repaired
* units spontaneously vanishing in various circumstances
* muti-player netcode (apparently) having much room for improvement
* secret weapon techs sometimes taking an age to activate (while the AI gets access to them instantly...)
* splitting armies up at midnight (apparently) leads to the newly divided army vanishing
* units stupidly retreating to the most ridiculous provinces
* And more I probably just can't think of right now (adding more as a I think of them, edited once so far)
