Not even close. Rare level. In the final stage, I lose one hero before even reaching the last round. Closest I came was killing two bosses, but I had just one near dead hero left and no more battle items (which are next to useless anyway), so obviously that last boss made quick work of me. Most other games I only kill one boss… barely.
All 3* heroes are maxed, and they’re the only 3’s I have, so it’s not like I can do any swapping. I intentionally maxed my 3’s first just for these godforsaken events. What I didn’t do, though, was have any 2* troops leveled – I fed them all to my 3*'s, not knowing that there’s a 2* max on troops. Not trying to be a whiner here, but I did everything I thought I needed to do to be able to beat just one level of the next event, and I’m still hitting a brick wall. Not even gonna try the other levels, because I don’t have a full team of either 4’s or 5’s. Very discouraging just thinking about how much more time I’d have to spend to luck into the right combination of 3* heroes to beat one of these things, and get them all leveled up sufficiently to do it.
