That word 'balance'. Dukla and Arad will get tweaks because to 'balance' gameplay. Like Im playing PR or BF1. Im mean,thats why I like Sidi-hard struggle of Germans over arfield against invading Valentine and Matilda. Not balaced but realistic and some really awsome round I played over that airfield. Germans mostly manage to counterattack airfield. Its just players didnt found all tricks at playing this Eastern maps yet as they did Sidi all that years.
I tend to agree that balance isn't entirely necessary for entertaining gameplay. I like Supercharge and Pegasus pretty well even though I don't think I've ever seen the Brits win either of those maps in their current form. The key difference is that those maps always progress. The Brits almost always fail to take the last city flags on Supercharge, but the fight over the earlier flags is entertaining and they usually are able to capture the first few lines of flags, allowing you to fight in different areas of the map.
What's not fun is if it's so lop-sided that one team makes no progress, and the map devolves into a never ending fight over a single set of flags with basically no hope for the losing team.
