Question Regarding Experience Mechanisms

[Renathy]

Let's suppose that I have two unranked weapons and one rank 30 weapon, to help me kill any enemies. I only use that specific weapon throughout the entire match, because the unranked weapons aren't really combat efficient.

 

Do my unranked weapons gain 100% of the experience my max. rank weapon gains, or does it still gain experience, regardless of its level, while only sharing a certain percentage of experience with my unraked weapons.

50% goes to the weapon you killed with, 50% goes to your warframe. Killing with warframe power gives all exp to warframe. The nweapons get nothing. You can either level them in weaker areas or join long-term group missions like Defense or Survival and have your weapons gain residual EXP from teammate kills while you can still use your ranked weapon to stay relevant.

[Scherhardt]

Nope they get nothing, unless you have a squad and get shared XP.

Affinity gained from affinity balls, challenges, casting abilities, and miscellaneous things (like capturing the capture target, rescuing the hostage, hacking a terminal, reviving allies, etc.) is counted the same as ally kill XP so it's split 4 ways between your warframe and three weapons.  Not equipping a weapon allows your frame and the other weapons to gain more XP.  Your sentinel and its weapon do not leech XP from your other equipment but get their own copy, so don't worry about those.
