Low Experience?...

yes, same here.

id like to know what's going on too

Bot kills and people kills give the same exp. And with how good their aim is, it should stay that way.

Today, I was playing steamblaster scientist and my XP feed was showing

+0 XP Healing

+1 XP Critically Heal an Ally

+12 XP Resurrection

+37 Vanquish

+43 XP Vanquish streak

+6 XP Assist

...amongst other things. Between 26 vanquishs, 6K+ healing and 7 revives, a total score of 1837 seems low. I don't know if it's a display bug and I don't know how much Total XP I got to determine if it's an XP bug or a display bug (i.e maybe it's the feed showing the wrong numbers). 

EDIT:

@SolidSnakeRN I would suggest creating a post in the "bugs" section if you haven't already. This can impact XP leveling rates and prize bulb earn rates. 

@SolidSnakeRN Hey, adding to this bug report may help. 

Also I'd be interested if this just happens in Suburbanation Isolation, or in other game modes too?

@EA_David not OP, but my XP numbers I listed out were while in the suburbination isolation weekly event. I wasn't paying attention in TT today, but yesterday I had the normal XP streams (+50XP for revive, +25XP assist, +150XP vanquish, etc...) in TT

@EA_DavidI've got this bug evverywhere, even in giddy park, and other portal game modes.
I've got acount on ps4 and there everything works normally

From XP machine in giddy park i've got normal 2000 XP

I noticed exactly the same thing. I decided to use Steam Blaster Scientist today in the new event for this week, Suburbination Isolation. I was getting 0 XP for healing and 1 XP for critical healing. That’s all I noticed. I only played the Weekly Event today, if that helps with anything. I disregarded that and thought the game was deciding to dock my XP, because I don’t know ... I was using Steam Blaster or something... 

Thanks for the extra info given.

Mixed mode and Ops where working fine.

I noticed that going drom the weekly mode to giddy park made it have low exp in park. But if you do a mode where its working correctly then go to giddy park you get normal exp there.
