According to the Internet Space Marines are THE worst army in Eighth Edition. I am planning to bring my Ultramarines to a large GT in SoCal next month. I have been practicing with my army since I first started to build it over a year ago. In my opinion while Bobby G gun-line is no longer a thing (which is a good thing) Space Marines are still okay and can get the job done. Sure they are not top tier but what about players that want to play what they love and do well with it.
The GT I’ll be attending is using the ITC Missions which is pretty much all I play. I have heard SoCal is a meta for 40k but I come from the east coast. I look forward to facing off against xenos and Knights. I should mention I have some allies but Ultramarines form the bulk of my list. I will post some more leading up to the GT plus a report on the event.
