If 1, then what to do in the meantime? If 3, then any suggestions for how long and what I can do in the meantime? If 4, then something that gives me game-long solidarity in Vi again.
ithink you should try other jg champs in normals or just play vi in normals and get used to it more such as quicker routes. Also since i don't know how your matches are you ganking enuff?
Change your build for vi if you want to carry or be a threat. Look at my last games on op.gg and look at damage report. I'm almost always, win or lose, the top damage in a game. Teammates just need to follow up.
It's XJ9s "dat vi" build, Google it, and if you don't know xj9 just know he is the jungle God of NA
The answer to your question is a combination of all four.

I think you should pick up voli and Sejuani in the jungle more, and consider looking into better itemization for the team you are against. You don't need to go randuins, but instead build a Thornmail against a high ad threat or two. Second, I recomend mercs on nearly every tank Jungler when against any slows or other cc.
Try to pick up some other kinds of junglers if your a jungle main. I'd suggest 
, 
, and 
. Diana is one of the better AP burst damage junglers, Ellise is slowly making the climb back into jungle relevance, and Gragas is actually a stronger tank than sej is at the moment, because he has a better early game. Good luck though.
