I'm not liking the direction they are going. The last two events have been very difficult. I have spent only monthly & have nearly all UR's... but the grind to get them anywhere is just insane. I couldn't do the lunar event at all despite having a max team & could barely do the valentine event in any good time: 400sec per run. My f2p husband barely beat it with a max skill all UR lvl 60 team. You are alienating your low lvl / casual users. Story & PVP easy, but don't make the events impossible.
