I got 4*star "Marth". I'm done lmao. You guys should consider yourselves lucky, you actually have quality teams. My best is Ike (who admittedly has solo'd quite a few tempest maps lmao), Xander (he's okay), -Atk Robin (soon to be replaced with Sharena, hopefully that will be a breath of fresh air. I went all out to get his damage up, Tri Adept, swordbreaker, and it works alright in arena but in tempest literally every maps there's one cheeky unit with savage blow or poison strike to put him below the threshold) and 4* +1 Raven (to be replaced with Nino. She'll contribute much more, even as a 4*star)
Right now what I'm aiming for is
Ike, Azura/Ninian, Hector, Reinhardt
