should I change area?

I raked up GLD and MAR to 15, going to do a Pugilist and Conjurer next I am in gridania should I change to another area or just stay in the same are for marks purposes

I'm not entirely sure I understand your question, but

1) You can level up in any region you want, it doesn't matter which.

2) "Marks" as in guild marks? Guild marks have been abolished, so don't worry about those. Doing leves in one city won't benefit you any more/less than any other city.

sweet thanks

i dont know you Thaleon but i really think the area around gridania horrible to walk .
Uldah and limsa are easier and faster to walk by the points. its worth trying that
