Recently, I was the recipient of a nice bartertown trade where I got epic Kreoss, Testament of Menoth, and Severius. This might not seem like much but I'm a big fan of the epic models and their rules. In the earlier edition of Warmachine, I didn't play epics at all. My main reason was I didn't have them and the second was they had to be played in 750 point games. Now that they can be played at any point level, that's gravy!
I was thinking about it on the way to work, how does epic Feora sound in a mangled metal game? Pretty good right? Not only does it change the meta on a lot of levels, the models normally look better. The Testament of Menoth is a killer sculpt and I can't wait to paint the guy. Epic Severius is also really nice and I even like epic Kreoss. The one I'm waiting to see is epic Harbinger. It's going to be hard to top the original Harbinger but I think Privateer can pull it off.
The only problem with epics is getting use to their rules and abilities. It's one that I won't mind having to due and it by doing so, it should create some good games.
