It was pretty easy, just like always in EG-type events. Ended up at rank 478, 15 Million EP, 500 SEG Eliminations and 350 EG Eliminations by just soloing my own EGs during Phase 1 and doing 1 Focus "poeks" on SEGs during Phase 2 and keep soloing my own EGs when there was no SEGs present to use Focus for. of course, with the help of our "whales", like Tomaa, ARM, FCGIZero, Stickygel, Christofor, SZA, slonenok, CyxMeT, Chilling Farts, and other guys from top-50 Ranking.
Btw, I'm 100% f2p player lvl 66 with 1M base SED. Had only N slayers and an old R Beta Slayer from Christmas EG Event, Kimi Kashima (lvl 100 of course). I didn't even used my e-Gacha tickets this time at all.
Well, that works all the time, tbh. I can't recall an EG event i'd end up outside of rank 1000 and most of the time i was even above Rank 500 by doing what i wrote above. Though, i play alot. Basically, around 14 hours every day, and try to never let my Focus or Stamina get and stay full.
Stopped playing all Nutaku's games (and, thus, using HBC and other related forums) around 06.2016
