Think about it...
Shy and Connor are both students of ACHILLES. But they're opposites. Shay DESTROYED the Assassin brotherhood and rebuilt Templar Order. Then Connor came and under the guidance of Achilles completely obliterated the Templar existence ALONE against all odds and re built the Assassin Order. Both of them are the strongest of their own organizations (No assassin before managed to end all Templars alone like Connor. And no Templar before managed to end all Assassins alone like Shay)
So their one on one fight could be the most EPIC FIGHT ever! So,you guys choose who you think will win. Strongest assassin yet (Connor) vs strongest Templar yet (Shay).
And sth tells me that Ubisoft will release a game that ends their stories.
