A knife is considered a tertiary weapon -- i.e., you usually use your SMG/Sniper/Battlerifle as your main, fall back to your Pistol, and use your Knife as a last resort. We don't necessarily always go in that order depending on circumstances, but that's the plain "bread and butter" breakdown.
I actually had a slightly easier time with it than I did with the Emperor. If you can click quickly, the max ROF is very high with almost no penalty for rapid fire.
Well I use my knife almost as much as my pistol. The good old pistol-knife never gets old, the only reason that I have auraxiumed my knife before any of the secondaries is because I change secondaries all the time.
Knife is a powerful, underrated weapon. If you have trouble with melee, consider binding your melee button to your mouse.
For most, perhaps. Knife is the weapon with which I have the most kills. Second place is the commissioner with more than 900 less kills. https://www.planetside2.com/players/#!/5428010618019933809/weapons
The rules for a knife are not like any other weapon. The knife doesn't need to be equipped, so you always have it. Although there is always a pause after a melee attack, you can melee instantly after firing any weapon. It also does a huge amount of damage and is almost completely silent. This means that the knife shouldn't be thought of by itself, rather as a compliment to whatever is equipped. When knifing becomes second nature, it revolutionizes a player's CQB.
