I think it is time for FG to introduce Elite Spell boosts!!! I leave it to FG’s creative team to decide what they ll be … I like surprises :-)
My recommendation would be to get them via special tokens that are earned from events. The Alliance members that perform best (Elite Alliance members) will get the most tokens which will allow them to get the Spell boosts for a longer time or the Spell boosts that are stronger. As for the Alliance members that perform badly I guess they should be awarded the lesser tokens or …none at all
that could be a good incentive for event participation …right?
