Letos Vaishan, and of course, the lightning-fast Railag!
If we compare who is the best among these three, it's definitely Railag! It's unlikely anyone else could boost the initiative of their troops so high above the enemy's troops; only Railag can do that!
The opponent won't even have time to blink, and their troops will be gone! Or they will have disappeared from the ATB scale!
If I had to choose from the regular heroes, I would play as Vaishan! Because he has a great starting position, and the new upgrade for assassins is simply 100% effective against any archers at the start! And invisibility is a slightly overpowered skill!
