I like Magni at tank more than Boril. With Boril you can attack even if your team is slower but powerful. If fast Magni fires, it’s rather irritating. Of course it depends on what surrounding heroes you have. Boril likes to have a healer flank, but that doesn’t seem to stop high levels from one shotting him.
Magni is not a top tank, but still a decent tank.
Better then Boril? If both maxed, of course yes.
If Boril heavy emblemed? Close call.
Both of them are really weak against dispellers, which green is full.
If not greens, there’s still Sabina that is a healer and Sonya working around riposte that are easily avalaible.
Fighter skill is really good for defence and quite annoying for a fast hero like Magni, so i rather take him.
Miki is solely for titans, forget about defence.
Not even Frida is so good there.
Boril gives more time to get the dispeller running. If they trigger Boril and dispel, the defense hasn’t done much. But against Magni they still want to dispel very soon, plus Magni might have finished off an attacker. And Magni pulls further away from Boril if attackers are short on green in late war unless they take the risk of running mono.
Problem with Magni is chances are he goes down a lot faster than Boril because of his low defense. Boril serves me as tank for quite a while and I’m happy with his performance. For me, his role is to buy as much time as possible for Azlar and Elena who flank him. He’s quite a meat sack, withstanding lots of punishment. He also encourages green stacking while the main damage dealers are red. It works well around 2500, even higher sometimes.
