I run KRU fotp foe foo and zylo.
I feel like this is the best all around (TB/TW/RAID) FO team possible. I know there are definitely arguments for others and I do admittedly have problems keeping foo and fotp alive in str, but this team is good for multiple defenses in TW, flawless combats in TB.. can solo rancor, haha, tank raid is a lot of fun with foe if used correctly, I think my best he was hitting for 109k at the end... It will do big damage in p2 str... This is the squad you should build, Imo.
The funny thing is that zylo used to be the biggest damage dealer in the game (or close to it) in this comp all you're doing with him is using lash out so executioner can do his work. It's laughable how much better foe is when modded correctly. He is another one of those underrated toons I feel like everyone should have g12, alongside KRU of course.
I am sorry I got off track. FOE is you're choice, he is a must have on a good FO squad, there's no way around it.
