I think it’s a mixed bag really.
75% of posts are “buy this new thing”.
But for the rest there are some interesting features. The periodic painting tutorials with Mengel are very useful. I also enjoy occasional army showcases. There are the regular comics (my favourite is Neverchosen, some of the others I just don’t find that funny (Roll models, battle brothers I’m looking at you)). There have also been the character battle royale type articles, which were quite a fun read. I’m quite interested in the upcoming meta watch series as well.
Overall, I’d rather have WarCom there than not. Yes, it will show me what GW is selling, but I’ve rarely gone and bought something solely because of it being featured on WarCom. It may not be the true “community“ that people seem to want from it but that’s why we have forums.
