I had three "test" games tonight of my 1000pt list.
Game 1: Kill Points, Dawn of War vs Nids. This was barely even a contest. I got smashed pretty heartily from the get go, showing my complete inexperience with Marines. I got too close, too fast and didn't really use my shooting nearly effectively enough. I conceded around turn 4.
Game 2: Kill Points, Spearhead vs Orks. A draw. I actually thought I lost but killed enough characters and vehicles to get the draw. I only had 7 KP on the table total. Again, marines cannot last in assaults. They are a short range fire fight army. It really sucks that to get into rapid fire range they are getting assaulted the next turn though, especially when nearly every other army is better at assault.
Game 3: Kill Points, Pitched Battle (yes these were all random) vs Dark Eldar. A win, finally. Though, in the end I barely had anything left on the table myself. 4 Wyches decimated nearly two complete tactical squads in subsequent assaults. My scouts died to warriors after assaulting them. My scouts did the assaulting and bounced right off, even with a shooting phase before hand! The same warrior squad tied down my third tactical squad nearly all game.
So what did I learn? Marines are really frustrating. You cannot quit. You have to just hunker down and keep playing. Any changes?
The league DOES have a sideboard allowance. I am thinking a Thunderfire Cannon might be a good sideboard to replace the predator. Woulda helped against both the nids and orks greatly. Perhaps a dev squad sideboard in lieu of a tactical squad? *shrugs*.
I spent time and money already on these dudes. I'd hate to give up on them. Any tips from other marine players out there? My list is only a few posts down to check out!
