unless you take prestige classes to make yourself a full caster as a Bard.
I've said giving cool powers. Not limiting it to combat. A Barbarian with 18+ STR should get huge bonuses on intimidate for example and should be able to terrify weaklings just by staring at then.
Shadow Wizards in Athas had some social penalties.
Book : Defilers and PReservers:The Wizards of Athas - page 62.
And every arcane caster in Athas also suffer from a huge problem. PEOPLE HATE ARCANE CASTERS. You can't just spam lightning bolts left and right. You need to masquarede your spells as psionics. Otherwise, a mob can decide to kill you and the veiled alliance which you are a part probably can decide to expel you and kill you if you are in risk of exposing the "cell". At mid levels(9), the memorization hindrance disappears however, the social becomes stronger. Due the fact that Athas lacks weave, memorization and preparation of spells is completely different and more costly and risky. Since paper is a luxury in Athas, spell scrolls are often "improvised" and are extremely rare. Same for spell components. Note that on 2nd edition, magic users has only d4 hit points and a maximum of +1 of con, so a very low level Shadow Wizard
can kill himself in the memorization process. Yes, 2nd edition Dark sun is THAT brutal.
I sadly only played as a Wizard in Athas one time in a one shot(and was 3rd edition, not 5th edition). Wizards in Athas are far weaker and less versatile than in Forgotten Realms, Mystara and other settings, but the limitations makes then really interesting to play.
Sadly, 5E is removing score penalties from certain races and going in the opposite direction of "having disadvantages/flaws/problems". Instead of making using fireball indoors more risky, 5E decided to allow
pyromaniacs evokers to not deal team damage. And removed the prohibited school rule.
