i suggest you reroll. i was about lv50 when i rerolled. i suggest you take a look at sanahtlig's guide to find out what core SSR himes for each element is. once you reroll a core hime, buy a miracle ticket. then boom, you start the game with 2 SSR's. use your new acct to host raids and use your old acct to beat the bosses.
i started off from lv1 yesterday and by end of day i m lv 21 - i burned thru half elixirs cause i wont have need for them for a while.
