Well, unlike most lords, Roy IS the tactician.
Eirika obeys Seth, Ephraim makes it up as he goes, Marth listens to Chris, Chrom/Lucina to Robin, FE7 follows Mark, Ike listens to Soren, i think only Alm, Seliph and Roy are the ones that have the tactician "skills".
Which is not as useful in battle as raw combat experience, which Ike does excell at, but if Roy can plan around Ike and id comparable to Eliwood at his prime, he is not going to be that much far behind Ike.
And Healing. Roy can heal three times as well as falchion in terms of HP, and has the same defense boost as Ragnell. Not to mention his AP/Durability is high enough for Aether (even RD) to not be a one hit kill. And, i think Weapon uses are a game mechanic, and in 1v1 fights, i think it is not reasonable to argue either Roy or Ike would run out of uses on their weapons, and i am pretty sure Nihil does not negate weapon use skills either.
So yeah, i think i still lead Roy.
