you are full of , stop spreading lies...already tested %'s per kill on 3 diff servers...a live server, progression server and the event server...stop lying, you aren't helping anyone...and this brings a question up...if you are in fact getting an exp bonus, as you stated to be getting 50% instead of 150%, why are you even on here? and why would you defend them even tho you are only getting a 3rd of what was advertised?
Just learn from this point they use it as a false advertising gimick is all. I thought the same thing 150% but it turns out just 50% which is meh on phinny in my own opinion as 50% of slow = just barely better anyhow. No need to get up in arms...
a troll is someone who tries to help the community realize they are being ? dumb anyways to answer your question...its rather simple, you kill a mob and see if it gives the same exp or more
Random bonus of 1%-100% extra per kill, with unknown variance. That way it's a surprise for everybody!
