Your Morgan is what my MU is.  This is what I do.

MU - Dread Fighter = Limit Break/Agressor/Ignis/Swordfaire/Tombfaire

Morgan - Grandmaster = Rally Spectrum/Rally Heart/Aegis/Pavis/Limit Break

I kind of make one an offensive powerhouse, while the other a tank that can be thrown wherever I want and BOOST others without worry of being killed.

I'm still on my first playthrough and imo the pair system works great. The main reason why is so great is because by doing that you can marry people and unlock conversions and all that jazz, in a different setting the pair mechanic might not have work like it did in the game. 

I used it a lot just to make sure one character married someone I wanted, or to see a funny dialog. If that wasn't the case I might have not used it like I did.

I have completed my goal. I have created the strongest Owain ever
Look at these caps

Class: Dread Fighter
STR: 50
MAG: 54
SKL: 50
SPD: 54
LCK: 55
DEF: 49
RES: 57 + 10

Skills: Limit Breaker, Ignis, Lethality, Resistance + 10, Pavise.

Weapons: Missiletainn, Tyrfing, Bolt Axe, Book of Naga,Mjolnir

No self healing?  Could replace Resistance +10 with Lifetaker.

Lethality could be replaced for Armsthrift so you could use those weapons forever.

Tho if your not planning to do the final DLC, than what you have is fine.

With Limit breaker, sol is the better choice.  having a 50% chance of healing on EVERY fight offensive and defensive versus only recieving healing on attack.

Though of course we don't know who the father is, so can't tell if he cna even get sol or lifetaker

*Note to self, stop staring at Anna's swaying hips*

He has Ignis, kinda obvious who daddy is....

Sol/Aether is better in healing but seeing as how he chose Ignis, he would probably want to keep that.  With Lifetaker, he can keep Ignis and still have some self healing.

I feel that Morgan could be my "cheapest" character:

Rightful King, Aegis, Lethality, Lifetaker, and Limit Breaker.

Rightful King really enhances the Aegis (now 66% activation) and Lethality (24% activation) skills. And of course Lifetaker is there as my self healing skill (Sol would cause too much overlap).

While Morgan is focused on Offense, Lucina is more Defense oriented:

Pavise, Aegis, Aether, Rightful King, and Limit Breaker

Pavise and Aegis (68% activation) will keep her protected for the most part while Aether (39% activation) will both hurt the foe and regain the lost HP.

Oh I was confused with pair-up being characters adjacent to each other, not the actual Pair-up option in the game. In that case then yeah I only used it like once, haven't found an scenario where I really needed it.

I do agree that adjacent allies shouldn't attack enemies, sometimes you want them to attack and sometimes you don't, not really consistent. All the bonuses are fine imo.

Haven't played Fire Emblem 4 yet, there's probably an English rom out there so I might as well give it a try.

The same could be said with crits.  Nothing sucks more than planning out:

Ok three enemies in front of me.

Only my tank can take more than one hit.

But if he takes 3 hits he is dead.

Tho I can't kill them during enemies turn cause his focus on Def rather than attack.

*Positions self so that 2 enemies will attack, third will be blocked by his own army*

*Lands a crit on second enemy, third enemy is now free to kill me*

RRRRRRRRRRAAAAAAAAAAAAGGGGGGGGGGGEEEEEEEEEEEEE
