That's how most people start out. It's a slippery slope.
I'll just point out that the list wasn't for you, more of a general idea for people who are still playing Space Marines in 6th when the meta has clearly moved on. Especially since the Death Star is over 1000 Points and doesn't even have Troops yet. Although with Kahn at the helm you can just Reserve/Outflank all of your Scoring units so that they don't get killed immediately.That looks like a cool list. I like SM bikes
Also, the new Helbrutes coming out look awesome, they even come with more than zero options! Unfortunately, they're still Helbrutes, and about a year too late.
