Recently got my sixth rings and now I am thinking of which hero of my roster should I ascend next. I have a second Marjanna (first is maxed) and last month I pulled this Jean-Francois guy. None of them will take a place on my raids team, as my current raid team (Sartanna, Grazul, Telluria, Magni, Joon) works pretty good most of the times. My two healers work very well together so none of the above is considered to take the place of Grazul. So, I would ascend one for wars or campaign. My team uses blue as center hero, so no need for a good red tank (I also have QoH for this if required).
Marjanna is pretty straightforward and solid. Satisfying (not super good) att/def, nice hit, fast. In wars, she takes someone not full-health out with ease.
On the other side this French guy is AoE, pretty weak however. Also, its special is effective only against specific heroes like Kuchen, Isarnia, Grimm etc. On quests I use Elena most of the times due to strong hit and counterattack, with some aid from mana potions. All things considered, I cannot find a good use for this guy.
What is your opinion? Glad to hear.
