So, I have 3 five star Tikis because I have the worst (best?) luck. My level 40 Tiki is very strong, and my 5 star whole team can basically take on any advanced arena team (Azura, Abel, Tiki, and Takumi), with only having difficulty with Robin. I could just sell the two dupes for 2,000 feathers in total. When I try to merge two Tikis, all Tikis give the same stat boosts: +1 Def and +1 HP. Does the stat boosts stay the same, so it would be in the end +2 Def and +2 HP? Would it be worth it to merge or should I get the feathers so once my beloved Kaden comes out (if ever) I can upgrade him?
