I've said it before and I'll say it again, nothing is more awesome than spamming Space Marine Dreadnoughts via the Orbital Relay into enemy territory and watch them go ape shit. Countless ways for them to kill.
Say, random question for DC players. I'm having trouble against necrons. What are some good counters to necron warriors? So far, I haven't really found anything that efficiently take them down. I usually play as the orks, but i'm curious what is good for other races too.
Hate them... You can outnumber them because they have high pop cost. Also, morale damage helps, but just fails against all else necron. If it's late enough, get area of effect units.
I just go for Dreadnought spam. It murders EVERTHING. Don't forget to max out the Orbital Relay que with backups.
