My feedback on the Brogni fusion
It's pretty clear that with each of these events, Plarium is tweaking their algorithm ever so slightly - trying to find the right balance between having it be too easy to get monstrously good champs vs having the reward not be very interesting while having it be more easily accomplishable.
This event seems to be their latest at trying to find the right mix. Brogni is indeed a very powerful champ from the looks of it, and the event is certainly much more challenging than their usuals.
I think they are pretty close. I feel like this almost strikes the right balance, however it's a bit *too* restrictive this time around, as every single one of the events needs to be completed in order to get the fragments.
Personally - I think they should continue to follow this model, but perhaps with a single extra event for each fusion - so if you do miss one, you aren't completely stuck. In this specific case, for example, the Summon Rush event is going to tax me to my limits - I'll still get it, but I wouldn't be able to if I weren't pretty far end-game already.
