User blog comment:NickNig/Mariudeth Leaderskill Question/@comment-25251916-20141003041054

The leaderskill of these both units are fairly different as they have different increases to the damage of criticals. Zebra enhances critical damage by 300% while Mariudeth only gives off a 100% increase. So let's say criticals are worth 150% of the normal damage. Zebra bumps that damage up to 450%, meanwhile with Mariudeth, you'll only experience a 250% increase in your damage.

The crit chance buff for Mariudeth at max SBB is only at 45%. That's on par with Aisha's crit chane buff but Duel SGX delivers a higher crit chance rate at 60%. Crit has a hard cap at 60% and all units have a 10% base crit chance.

Note: At 5*, Mariudeth with a max BB only gives a 30% crit chance rate so it's not really optimal.

Personally, I would still stick with Zebra regardless of typing. Crit teams do rely on one hit KOs so I rather have a team centered with the highest damage possible. Stick with Duel SGX for crit buff, nobody topples his throne for crits. Mariudeth is more like a niche unit.
