Uses for gold when levelling a team

[Homer]

For my healers and caster I made

https://classic.wowhead.com/item=100...amweave-gloves
https://classic.wowhead.com/item=10021/dreamweave-vest
They lasted into dungeons at 60 for me.

For my warriors I made/bought this and put +100 health on it, lasted untill I bought plate items at 50 or so.

I think those items make sense for your healer, but if you are using AoE spells like for example AE it only gets 14% of the SP so I tend to go for pure int.
