1)Is a White Scars army even suitable?
Yes. Very much so. They are fast, hard, tough, and cheap for the points. You can get a 8 man bike squad with a attached Attack Bike for 255. Then you upgrade to a
PF and meltas and your at about 300. A tough hard unit that can flank when you use khan. Take at least two units like this in your army.
Also take a command squad with can and take as many power weapons as you can in the squad. Throw in a few storm shields for taste and BAM. You have a T5 jump infintry that have
FNP, Furious Charge, Hit and Run, Flanking, and 4
PW attacks each on the charge. Throw in a few of those 3+ storm shield
inv saves and they are about as tough as a Jetseer Council. This is my favorite part of a white scars army. Add a naked chaplin on bike for some rerollable attacks on the charge and nothing will survive there charge, and if they do you hit and run and charge again.
The command squad is about 300+ points depending on toys and khan is 200ish points so that is 500 points. Add in the two bike squads, and that is 1100 points. Then just get speeders and attack bikes to fill out your list.
Tactics would be to keep everything in reserve and flank or deep strike everything. Combat squad the troops if needed for 4 troops choices.
I love the new white scars army list! I will be picking up about 3 of those ravenwing boxes to get my army started. I just love how fast and hard this list is. Very fun to play and its cool to have your own little bike gang. I think i am going to do mine as hells angels or something. Everyone will be rocking leather badges, chains, and maltof cocktails.
Good luck with your army and you should defenetly start playin, with this army every game is a blast even if you lose.
