Umm there are rumors saying that u can continue bursting even if u are lvl 180+.I tried to go with my hole team in maya and in other places where i fought against high lvl wind mobs.I had an earth in my team which used terra in the 1st round so the pets didn't die.However the exp which i got from bursting at beetles was higher(150-200) than the exp i got there(150 max).I'll try the debuff/buff train at turtle island and i'll post what i got.^_^
Note:I did my tests during x2 exp event.
