We should really wait with topics like this one until we see at last one patch that will bring some big changes in EA ...
Not just hotfixes ...
There is also possibility, that XP gain was boosed for EA so players can actualy try and see all features that was (1-4) prepared for them ... but enemies, and XP will be changed in full release, so we will he happy if we reach level 3, or get just nearly close to level 4 with whole act 1 complete.
