That’s a good way of thinking about it. Raid defense is uway* down my list of priorities. Offenses (and player technique) has gotten so good that it’s not plausible to hold top 100 for more than an hour. It’s a good night if I’m still,over 2600 in the morning. (Actually, I’m happiest when I’m below 2500 to start, as it makes filling my chest all the easier.)
Frida created a space for Thorne: a Frida-Thorne 1-2 hit is very effective on raid/war offense. With emblems, he’s pretty effective on defense, too, though he doesn’t pose any special risk.
