I know that this is kind of late to be suggesting things, for obvious reasons, but what I'm suggesting is minor, so hopefully it is feasible to include in a patch.
Griffin, Rahel, and Arman all learn upgraded versions of their attacks that have much higher damage multipliers, but greater costs -- Double Strike, Trueshaft, and Mega Stab respectively. However, Rajav, who is mostly a simple melee unit, does not get anything like this however. Would it be possible to give him some form of equivalent? He really isn't good for much else, and since he and Griffin are so similar, it seems a bit imbalanced to only give one of them a major damage attack.
