Im trying to prioritize my leveling or current heroes.
Currently working on:
Red - Hawkmoon
Blue - Jafir
Purple - Cyprian
Yellow - Chao
Green - Orla
Normally when i get good 3*, I pause on leveling 4* of the same color. Im working on finishing Orla and Chao, curious to see who youd work on next in each color. Was thinking Shrubbear on green and either Wu Kong or Gretel on yellow.
Lots of nice options for green: Faiez, Shrubbear, Carver, Whacker, Melendor and Caedmon and if you need a tank: Kashhrek is a very good option early on (looses importance later on though, while the other 4stars will be useful forever)
Yellow: Chao is OK for now, but won´t be used much later on. The fast mana steal can be useful when cleaning up a hero during war, but the weak hit makes him not useful for serious attack teams. So better to go For either Wu or Gretel, both are much better, even though for very different purposes.
Red: Hawkmoon is OK, but will be great when you get the costume, so nothing wrong with upgrading her already. Mack is a decent option for counterattack in a second colour.
Blue: Karil costume is a good hitter for 3 stars. Lemur a decent healer. Kiril one of the go-to healers, so absolutely good to have (also works well as tank early on) Boril is a decent counterattacker. Jarif an OK sniper (would do better with defdown, like Valen)
Purple: Cyprian seems the only option? Well then go for him, the other colours have other options, but nothing wrong with having 2 or 3 counterattackers early on those are your way to hit above your own weight class.
Renfeld is useless, but hsi costume is really good, so if out of options you could upgrade him to be ready when you get the costume.
