I have used Ettins in SP only. What with no hammers and bad starting equip and high enc. they are serviceable but don't shine. Perhaps a tad expensive for what you get. Which is not necessarily bad for not all magic variants should be the same (i.e. Fire shines in evo. Death in summons etc).

I saw Shishis in action in MP. They are right on the mark. SC wise they're a glass cannon. i.e. can kill a SC but OtOH die to numbers of lesser units (like GR). They serve to fill a much needed lack in this niche.

No idea re. the rest, never had the chance to see or use them.
