Can I main shaman?

1) Honestly I have been wondering for alot of months about this , I played all characters as pve/pvm ( exept ninja ofc ) I had no fun playing with any characters except with shaman , but Can I Have him as a main character? Not as a side/support for my main character? I think he gets a bonus if he used a buff on himself?

If yes

Healing force or dragon? I know indeed that dragon has an advantage against metin2 stones or fighting on mount generally , but healing force after unlocking 4 master skills Becomes op on ground , that being said is my question, can I just play on ground mostly and poke with swiftness ? More of a mage playstyle , and one of the main reasons I don't want to be a dragon is Whatever character anyone plays he will always have a dragon shaman for support.

Fan or bell? On mount bell On ground fan But if Im ever gonna play healing force as pve/pvm should i take bell or fan? Bell = more dps especially on mount Fan = more magic damage ( which is what im gonna do on a healing force shaman?)

Thanks in advance!

Thanks for all the replies,but can anyone who has done this before say his opinion?
