Yeah a lot of people want a game where you can kind of just roam around and explore all day and have battles come up in random squad vs squad or 1v1 skirmishes and then let them expand into huge battles.
Unfortunately it sounds like Huxley will have instanced battlefields so there won't be that exact kind of thing happening.
However I'm pretty sure we'll be able to get the same feel as if we were just roaming around and happen to stumped across an enemy patrol. The 100 vs 100 maps will be huge so there's no doubt we'll have to do a good bit of scouting and traveling in general from place to place so there is bound to be some squads running into each other at random and creating a hot spot on the map.
We can all just hope for the best until the game comes out
