Good questions! I’m away for a few days so don’t have access to the game to try sr90+ tanks in the new patch, so let me get back to you on that front.
I would expect some lightning retaliation vindicator build would do incredibly well. Or, check out @Crab_Turtle_2112 's tank , tho I’m not sure how itwill go in 1.2.0.1
Re: the medal, War Cry brings 35% damage reduction, which doesn’t stack with other sourves, so it makes sense to bring a different medal.
