As with what Leminno said, which I'm going to have to agree with; there's a lot more to how Survival is than just "it's toxic and not very friendly". The server itself, as a whole, is quite welcoming but it isn't very kind to newer players outside of that. Constantly I see questions go by without people answering them, and/or people who just simply don't care and trash talk newer players for questions. No, this isn't a common occurrence, but it happens enough that I've taken note of it.
Survival itself, from as long as I've played here, has been a fairly dramatic server. Honestly, sometimes it's to the point to where I feel like people are just being melodramatic; some people take things so small to heart and make a much bigger deal out it than it should be. Aside from that, the drama is about on-par with other networks of similar size, and sometimes, even smaller servers. Hell, I've seen smaller one-gamemode servers have more drama than Mana has in the same amount of time.
Basically, with what Lem said, just focus on yourself and try not to keep toxicity in. Don't get involved in the drama if it annoys you, since I know some people actually really like the drama (lol). Honestly, though, there is something going on whether it's an argument, some petty hate, or this or that which happens every day; new things cycle in and out every week. There's almost always the same, or a similar group of people making or at least taking part in the drama/toxicity. Again though, that's just how servers are; every network I've been on has had toxicity and drama, Manacube isn't any different.
Eco wise... I'm sitting at 16mil and I'm fine with that, it's enough to buy what I need from /shop for building and stuff, so I'm not really complaining. I don't really know how the eco is, I'm not very competitive with /p top.
