king is wrong.
here's my short statement in plain egnlish
What they did is they nerfed the XP gain in all the 51+ levels except for the 54 and 59 hell levels wich got a pretty big bonus ... the net result of that is that you need exactly as much exp as before to get from 51 to 60 .. you just have a much smoother ride along the way.
They ONLY changed the xp flowing into your normal xp bar ... the AAXP gains are not subject to the modifiers they added to the normal levels so they're still the same as before the patch.
What fee is saying is " WHAA .. they slowed down the normal exp gain at level 60 so they must have nerfed AA XP also." without testing AAXP ....
AAXP gain is still the samed as it was before sept. 4th
Really short version:
The slowed down xp gain at levels 51,52,53,55,56,57,58,60 to compensate the increase of XP you get at levels 54 and 60 in such a way that you need just as much xp to get from no xp in 51 to pull 60. They did not do anything to AAXP other then restore it to the values before sept 4th
wish some level 60 with show EQ would run a test with AAXP turned up to 100%
