I fought wtf, but opened russian forums and saw this:
Personally I am against changing things, but I like this change if it's true. Palaika/7sign quest make lvl up from 79 to 85 too easy and speeds up the gameplay way too much.
If this change is real, people will must grind level instead of getting free exp from quest. It's a good thing for people who can sell exp.
All changed RPG did before launch yet is nice and will make server lasting longer. Sieges in the end of december, auction january. It's perfect if you want stay at same play longer than 3 weeks...
