You guys are not helping me, if you guys think this current rebel mechanics is fine then you shouldn't be talking here. This thread is not a spam, I am serious with this topic. Rebels ARE Overpowered.
So it's "agree or leave" then? No mate. Rebels are pretty much fine, it's a fine balance between unstoppable and challenging but it's about as close as we're going to get without tweak after tweak after tweak. You're handed many opportunities to handle Rebels before you actually have to confront them and if you don't take them then that's your problem. I'm currently getting kicked around my swedish provinces by Norweigan and Catholic dissenters, It's going to cripple me for the next decade but instead of crying OP I can honestly look back over everything I've done for the past thirty years and see how I've mostly caused this problem myself.
As far as morale and discipline are concerned, for the first half of the game all an army consisted of was the same semi-trained guys who would transfer that talent to the rebels cause if they chose to join. The problem was leadership which we have modeled in a fashion, and equipment and supplies, which we don't. If we *really* wanted to change the ways rebels work now the best change I feel we could make is a dissent metre within your army regiments.
