To me, the epic strike events is one of the most exciting features of this game. I play since May and during the first epic events my team was pretty low level (about 11-13 maybe), so if I didn’t come up with some extremely fancy and thoroughly worked-out battle plan, the level 30 monsters would to just wipe the floor with my dinos. Since then my team has of course evolved (highest Stegodeus 20 and Indom 20 now, no Spinotasuchus yet) but the towers are still extremely challenging most of the time, such that I succeed only at half of them at the first try (and another 25% at the second). In fact, I already find myself thinking about a suitable battle strategy the days before the actual event, as soon as the monsters have been leaked during the week.
Thank you Ludia!
