Is grand coven bad?
Hello, I am pretty new to the warhammer game and witha friend we have been dying to try it for some while. I havent played yet and I dont know so much about the rules, but I know a little, so I started investigating what to do and how to play thousand sons, because I find them awesome and I love their lore and I also love Tzeench and the rubric marines. I adore it. But when I saw every recommendation, it said that grand coven was the best detatchment rule, but when I read it for myself I found it was not really that good. At least to me. I found that rubricae phalanx was better and had more buffs, but I also want to understand fully why everyone puts grand coven as their detachment rule, and I also dont want to always be conditioned to use rubrics as my main everytime, and use more of the weird tzaangors and daemon princes.
If someone could please explain it, or give me some advice, I would appreciate it really much.
Thanks!
