There are actually a couple separate Locations where the XP requirement increases, first at level 1850 and again at 2500, so this is totally normal.
yea its normal that happen to me a few times already on viking clan think it was something around 3200 or 3300 been waiting to see when i get a bigger jump in exp currently at level 3984
It has not stopped anyone from advancing one bit, so disagree with it being an unappealing facet of the game.
put it this way the exp might have doubled to level but if you haven't noticed yet when you help out players challenge help that also got bigger for you to help level you up faster and as Kristen stated above it hasn't stopped anyone from leveling....but as you progress higher up in level it will do it again multiple times
changes in xp for challenges are a joke its the same no matter the level it is based off % and that never increases so yes the xp for challenge does go up but its still takes 100 of them to level no matter how high or low so you cant say it gets better just looks better thats all. The % payout is the same thats what matter not what it shows.
i didnt say it didnt but the way you guys put it, it got better but when it takes same amount to level its no better its just a eye trick gimmick is what i was trying to point out, thats all Kirsten
