Rhino is really slow. But his damage buff is excellent. I personally like Vauban more but as other ppl said not very beginner friendly.
Your top priority should be finishing the star chart und reach at least MR8-ish. A lot of good weapons are avaible then.
Always max you weapons and frames, even if you don’t like them. use your platin exclusively for frame/weapon slots
That would be my general advise for a beginner

Nekros is superb for ressource farming. I would go for it
First of all: We need more people. After that we can decide about rules.
That’s just my opinion of course
Only if you want to push MoC.
Who is gonna pull?
It’s standard on Fedora already. But I remember first hearing about Wayland many years ago. So, definitely Kudos to the Devs 🙂
