I totally agree with the strategy of throwing a +1 on almost every maxed hero to take that chance of their Talent activating from zero to something. Also like and agree that +1’s on 3*s are cheap and essentially free to reset with Gems.
My general philosophy after giving everyone a +1 is to spend Emblems on the 5*'s that are on my A-team (Elena, Evelyn) who get used for Maps, most Raids, and Challenge events. But 5*'s are Emblem-spensive so after that beef up the 4s that go to War because you can do three 4’s for the price of one 5*.
Grimm#1 +12, Grimm#2 +1, Namahage +1
Rigard +11, Kailani +1, Hawkmoon +1
Ariel 3-35, saving current Emblems for when she maxes; may even reset Rigard for her
Kunchen 2-60, will get a +1 eventually but he’s backed up in my Purple leveling queue
Caedmon +10, Melendor +1, Belith +1, Brienne +1
Kadilen 3-55, saving current Emblems for when she maxes to go at least +1
Elena +6, Boldtusk +1, Valen +1
Eventually Magni 3-70, Colen 4-32, and Panther 1-1 will all get +1’s
Wu +18, Wilbur +1
Joon will get +1 as soon as I get 58 more Emblems
Queen of Hearts +2, Richard +1, Tyrum +10
Tyrum likely needs a reset, he was my only option for a long time.
Evelyn +5, Buddy +1, Tiburtus +1, Berden +1
Marjana 3-70 is waiting on Rings and will get a +1 eventually
Musashi 3-33 and Kelile 3-60 would get +1’s if they ever max, but I’m not sure they’re worth maxing
Sabina +13, Jahangir +1
Morgan 3-70 would get a +1 if I ever max her
Proteus +11, Kiril +1, Ulmer +1
Hel 3-47, saving all current Emblems for when she maxes
