"For what they are they get an insanely high amount of pracs - and hp by extension."
This bonus is overrated.
Gnomes can be the following classes:
Bard, Warrior, Ranger, Thief, Invoker, Battlemage, and Blademaster.
Stat Maxes:
STR: 18 INT: 23 WIS: 25 DEX: 18 CON: 18
They got bad STR,DEX,CON for meeles.
Their 25 WISDOM means 5 pracs per Level. Meaning they have an extra 100 HP's from the extra 2 practices.
You can argue that high INT also saves practices. All, lets imagine a meele has 50 skills, which they do not.
So they get +150 HP's from extra practices over lets say a human.
But a human has +2 CON points. That around +75HP's or around it.
So now you have a 18 STR/DEX human with +75 HP's and a Mental vulnerability.
Human:
21 STR - more Hit/Dam, more weapons to wield, more carry weight
20 DEX - Average Dex
20 CON - average Regeneration
Bonus to magic items ???
Gnome:
18 STR - less hit/dam, less weapons to wield, weakened defences/offence
18 DEX - Worse AC, Less 2 items, weakened defences/offence
18 CON - Slightly worse regeneration
Bonus + 75 HP's
Mental Vulnerability
See, you are better of playing a Human.
