FOR THE LEARNING IMPAIRED:

EVERYONE has a level cap on swimming. On Iksar, you get 100 as the base,
rather than 0 as the base as with every other race on Norrath. The
Progression remains the same, 5 for ever level. Meaning a Level 5 human can
reach 25 swimming skill, BUT a level 5 iksar can reach 125 skill.
The only skills without level caps are the trade skills (Fishing has a cap
though).
Humans get no XP bonus, general consensus is that Error in coding gave bonus
to Halflings.

Iksar have massive disadvantages to counter their strengths.
Trolls have a 15% RACIAL XP penalty. The previous quoter was
mistaken. 25% is the penalty for troll (15%) and Shadowknight (10%)
Iksar have a 20% Racial.
An error allowed the Iksar to be non KOS is a few places... This
error was changed on 4/28. Iksar are now KOS to everything, even vendors.
I am not sure if this is Threateningly or true Scowls KOS. If it is Scowls,
then there is no way for them to increase that faction. As it is now, there
is only one zone in Antonica that Iksar can be bound, Arena. Only one in
Feydwer, G. Feydark. And unless something new has been found, Kunark has
only one, Cabilis ( actually more than one zone, but the difference is
negligible ).
Iksar monks lose most of the Natural Haste of Human Monks.

Iksar will be powerful monks, and powerful in any class save SK (smaller
size only advantage, but countered with lack of slam/front stunable), but
Iksar will not be replacing any of the other races, even Iksar monks.
