Solo gearing options for a wizard?

[Garnaak]

Looking at the magelo, you are geared very well for a non-raid-guilded character. You could possibly start swapping int for raw mana items to maximize, maybe hp items (if you are taking hits while quadding)

Some suggestions to give examples: Golden Chitin Bracer for Supple Scale Armband, Ice Silk Legs for Tanned Iksar Hide, GBS for Drachnid Thyxl

Appear to be doing quite well to me, don't see any issues here.

This server is so old, with so many people that have many 60 lvl toons, you see lots of lower level characters who have been able to loot HoT/NToV/Other loots well before those characters could help with the actual content. Don't compare your character to those ones.
