Experience of Mobs

[Bastion]

Is something that i saw today trivial mobs give me experience when would must don't give me really. I don't know how works the experience formula on official server but maybe like this:

- Trivial -> No experience
- Effortless -> 10% base experience
- Easy -> 25% of base experience?
- Equal -> 100% of base experience
- Dangerous -> 125% of base experience?
- Deadly -> 150% of base experience?

How i said, this is only percentages invented by me, but today in low level PQ i gotten experience nearby to level 31 in a PQ of level 13.

Will there changes in this?
