I normally use medium armor, and if I want to be extra fast I use light armor.

Don't get me wrong, I like the looks of chunkier armor, it is more my style.

But what is the use for heavy armor? I understand you are tougher to kill, but I am always left behind because it is slower.

Also I am still thrown around with explosions and I can't still be killed easily when overwhelmed, which I can avoid with medium or light armor by just healing constantly and running away.

So in what situations or what is the tactical advantage of heavy armor?
