INT, WIS, and STR are probably the easiest stats to max in classic EQ. STA, HP, dex, agi are all harder to max with classic gear. Most reroll twinks focus more on STA/HP and less on primary DPS stats because they can make those up in gear. If you are a new char on the server that will be untwinked, you are better off being more balanced between DPS stats and STA/HPs.
For religion, you are safest being agnostic when you are able to. However, there are a few cases where religion is good (the following list is not comprehensive):
- worshippers of Innoruuk can quest a
haste neck clicky.
- HIE and HEF Tunarian paladins can quest
Nature's Defender in Velious (Plane of Growth).
- Worshippers of Rallos Zek supposedly have an easier time with the giant faction in Velious.
I'm sure there are other reasons to pick someone other than agnostic, but agnostic is always a safe bet if possible.
