It does not matter what race you pick.
All have advantages/disadvantages.

Look at experince and starting stats.
Four things to consider. It is hard to cap stamina on gear alone until velious
raid gear if your not an Ogre. Ikkies have small ac/regen bonus
and trolls have regen bonus. They not that important once
well geared though. Weight penalty for lower str when low lvls without twink gear.
The last thing to consider is exp bonus/penalties, small
races having bonus and large having penalties.
Stat str/stam/agi/dex in that order for small races.
Stat agi/stam/dex for large races.
Str is easily maxxed late game, dex/stam being a second close during Vel, and the agi being hardest to max with the str/sta being priority.
Diety (RZek always for cultural gear though not important unless Luclin is released.)
(Someone also mentioned slam, alot of mobs past 50 become unstunnable though I am not sure if the slam mechanic adds aggro for its stun chance???)
