So do you have any need for stealth or is it just dodge and counter still?
stealth actually plays a big role in some missions and is a better way to go about it. I remember that in AC3 you could almost never use stealth effectively you would always have to fight your way through things. But now stealth is a good strategy to use. There is one pain in the but mission though that you can't kill anyone and you can't be detected. IT took me a good hour to get past this one part.
also there are restricted sections on the seas. you need to use avoidance on these levels. The last thing you would want to happen is to have a level 23 fridget see you when you are crippled. Also with fighting at sea you have to examine your surroundings. A couple of times I wanted to pillage a ship because it had materials I needed but two other fridgets where lurking around and came to fight me putting me at a disadvantage causing me to by desynched or I had to turn tail and run. It is a nice addition of strategy when I remember from AC3 it was mostly you just follow the story line not much strategy involved.
