Yes with no oop(out of party) buffer it will be slow to exp/farm.But active supports are welcome in most clans.Imo best class to truly solo(self buffs only and past 76 lvl) even with no gear are the summoners.As others said find a clan that could help you with levels/items cause no matter what class you choose you will need their help as a newcomer.
Buying armor/jewels/weapons from NPC and restaring seems to give them Fire attribute
Trading them still give attribute.Combination doesnt matter.
How to replicate:buy any armor/jewel/weapon from Giran,after restaring it will give you Fire attribute.
Tested it on 2 characters,equipment bought from Giran and Aden will yield the same result.
