Agreed, it might be strong, but then again, we're talking of a 13SS model.

We can find a trend in the "extreme" melee powers of the game. Lord Chompy Bits, Lady Justice, Killjoy... all of them get Onslaught. There's an equivalent for spellcasters too. All of them have good Cb ot Ca and some can even use soulstones

I see it as an alternative to a complete reboot of the card (which i still would prefer), but this simple switch of trigger might be just what Nekima needs in order to reach an acceptable efficiency.
