Some misinformation in this thread.
PNP formula for xp to level is current level*1000.
DDO decided to make the numbers bigger for everything to look better for the MMO crowd. Formula was the same as PNP but times 10. To reach level 2 required 10k xp. Level 3 was 30k xp.
Between mod1 and mod2, they decided to count all ranks accumlative instead of only up to 4. So instead of being 10.4 you were rank 54(I think). This really didn't have the effect from the DDO players they had hoped because we still used levels not ranks.
They also decided to lower the xp needed to hit level 2 to 5k and level 3 to 20k total. This made leveling to 3 very quick for new players, instead of spending a week in the harbor or grinding ww 5+ times. They also lowered the base xp in ww/stk.
Euphonias has always given one rank of xp(1/5 a level). This was 2000 originally, and now is 1000. The quest xp is added after this xp. For experienced players rolling alts, everything in the harbor was made bypassable over time, except the wavecrest starter quest. After some complaining of the difficulty of Thwarting the Threat, they lowered the attack/ac of the mobs there.
They also added the solo quests, solo option to quests, and moved some quests around so new players could get a feel of the game without being unable to solo stuff due to build or afraid to group yet.
With the NPE coming out, I would withhold suggestions to anything low level until we see how it works out.
