XP were lowered few seasons ago, because people just camped their hideouts and crafted all night long. Gathering was static and highly abused.
It was not a big deal, because we had diminishing XP, so it was more or less equal. But then XP for killing were drastically improved and making a lvl 21 character was a matter of days(hours). Alas, crafting XP remained the same.
Im for improving XP for crafting in order to match them with XP for killing.
Moreover, Im for improving XP for using skills. Its ridiculous to receive 5 xp for steal, how can someone lvl up with it ? Same goes for lockpick, science, repair. I dont want to have only one viable option to lvl up a character - through fighting
