My alliance currently uses blue heroes for war tanks but is contemplating the switch to purple in the next couple of months, at least on a trial basis. That being said, which of the above mentioned heroes will best fit that role? I have Sartana fully leveled and emblemed, Domitia at 3.7 and Grimble just started. I have the mats to take one of the later two to final levels.
Please note I also have all of the classic four star heroes fully leveled including Cyprian however he will not be getting any paladin emblems as they are all on Frida who is my current tank. I also do not plan on doing any Atlantis pulls going forward as I want to save my gems for Season 3 (although I will do a couple of event pulls for a chance at the February and March HOTM).
