Honestly - yes, those two are pretty much trash right now, but I'd be very hesitant to ever use epics as food. There's no guarantee that in the future they won't be updated to be better, and if that happens, you'll regret it greatly, since getting them in the future will be much more difficult.

Ya but as it sits with player Power of 852,000 , my Opponents in Arena are Brutal 

Stuck in Bronze Tier I getting hamered by 20 to 30 players just before arena reset and driven back down to 900 Points in Bronze Tier I , So I am Eating my Storage , and just about everything else

that isnt a B+ according to Hellhades and Ayumilove .......

Kinda Sad we get penalized for Collecting heros in a hero Collection game

I am Wondering if Plarium coded it so as to Ignore the Storage where Arena is Concerned

but , then Arena Defense Teams in Storage would be Ignored ,,,, 

Arena Completely Sucks but it is what it is ,

 WAIT till the game Breaking New Clan Tourny Armor comes out

Then The Whales will start to holler and Plarium might start to listen

imo always keep atleast 1 copy of every epic you get, but dupe Lordly Legionnaire = food

Save your Knight Errant because you might need him in Banner Lords Faction Crypt.

- Knight Errant can hit really hard 

If I remember correctly, I did the following:

I used Knight Errant from Stage 1 to 13

I used Cillian the Lucky from Stage 14 to 20 

I used Conqueror for Stage 21 

I was stuck on Stage 14 which is the 2nd Boss.

I was going to level up my Knight Errant to beat 2nd Boss.

However, before I got a chance to level up Knight Errant, The game had a Fusion Event.

Cillian the Lucky was the featured Fusion.

I acquired Cillian the Lucky from that Fusion Event.

This is why I ended up replacing Knight Errant for my Cillian.

Save 1 of your Lordly Legionary.

- Lordly Legionary is a Fire Knight Progression hero.

If you find yourself stuck in Fire Knight, He can be helpful.

Lordly Legionary isn't a Stage 17 or 20 Fire Knight Hero

Lordly Legionary is more of a Stage 14-16 or 18-19 Fire Knight Hero.

As far as the Dupe Lordly Legionary goes, I think you can use it as a chicken.

I think you will only need 1 of him.
