At this point If I were u I would go with stamina. What Ive always done at the lower levels and for as long as i can is create a "loop". Basically getting enough stamina to where u can level at the VERY LEAST 10 times per stam refill....which allows u to play non stop for free. At your level it can very easy to exceed ten levels per refill....which is important because u also want to be able to get your chieftains. Its important to make a loop and take advantage of it as soon and as long as u can because at diff level intervals the xp u will need to level jumps significantly making a loop much more difficult if not impossible.
Its also VERY IMPORTANT to take advantage of every bit of energy, helps etc etc....never leave any xp on the table!
Since u will be focusing on bosses....try to add everyone...even your rivals...the more clan u have the more bosses u have available, this will allow u to be a bit more picky as far as which bosses u want to kill for the best XP. It also allows u to have much fewer players attacking u while u try to level and u wont need to focus as much on att or def.
Hope this helps...GOOD LUCK!
