Best C-skill for B! Ike

I've touched on this before, but Threaten Atk is EXTREMELY underrated on tanky offensive bait units like Ike, Hector, etc, especially compared to Threaten Def, which is best used on brave attackers like Cherche and Chrom imo. Since FEH uses "atk" instead of "str/mag", it boosts an enemy phase tank's defense on BOTH ends of the spectrum before the counter attack. And Ike usually hits hard enough that he doesn't need the debuff.

Panic Ploy is great on him if you don't have a higher HP unit to spam it on like hector or zephiel. His HP may not be unbelievably high, but it's still higher than all bladetome mages and most cavalry units as well, so it'll serve its purpose. Slightly redundant on the latter with Beorc's Blessing tho, so if running PP maybe take that opportunity to give him Vantage/Quick Riposte/Renewal, etc.
