XP Gain

I originally thought that you get 1 XP per kill, but then I tried out an experiment. I bought a Hardcore Playa's potion and I watched my XP bar go up by 3 after each kill. So, every kill gives you 1.5 XP? Or what? Also, what's up with the campaigns not giving you XP after 3 levels of the supposed level cap? Shouldn't they just stop giving XP? Finally, if each level gives XP 3 levels after the cap, does AO2 now give XP up to level 48? Thanks in advance for any answers!

There is a thread somewhere that cinco started explaining this....

one level after level cap for a level is 75% exp
two levels after level cap for a level is 50% exp
three levels after level cap for a level is 25%

so technically yes you could get to lv48 in ao2.. would just take much longer.

ok, maybe I am not getting something. If I use no elixirs, in AO2 for instance, I get 1 point per kill and in AO3 I get 1 point per kill. I had a level 45 character that I played till just shy of 46 on AO3, had to log off, then went to an AO2 map later for the last few points to 46. So, isn't it just 1 point per kill? If so, wouldn't it take the same amount of time to level in AO2 to 48 as it would in AO3 to 48 only with less hassle?

I am sure I am missing something.
