this is probably the best spot with Strawberry patch since its 3X Strawberry patches and it spawns everytime you relog.

In 60minutes i had 3202 Strawberry and round 9000exp ( using exp buff )
its located Beneth Kryta. as shown on the screen shot!
EDIT 1: Theres 3more above & right behind the 3x shown on the printscreen so if lucky theres a total of 6x per relog!
Edit 2: on the eges on all sides facing the water theres around maybe 13 flowers you can pick and relog on heavy overflows. tried this just now and keeps working
