That blue circle becomes easier the higher your level. At level 82 you won't beat it with less than 55-60k power, but the same circle is easy beatable with 43k power at level 88. if you can't beat it now just wait to reach level 86-87 and retry. Personally speaking i beat it in 2.0 with mei mabui tenten gnw azure fang lineup at level 87 with 45k power (at the time there was no charms and many less power ups).
