I'd be pretty confident they will convert seals into medallions, though i don't know this one way or the other.
My biggest needs for points are DPS/Moors melee weapon > DPS/Moors Jav > Tanking Weapon = Tanking Jav. you also gain almost nothing from upgrading to a 1st age LI for tanking, especially since (at least with my legacy choices) points aren't in short supply.
If I were choosing 1 for my only 1st age LI, it would be a melee DPS/Moors one, as that is how I prefer to play in the moors, and my legacy choices leave that the most in need of points. If you are more of an Assailment Warden in the moors, the dps rating boost is probably worth it to take a jav over melee weapon.
