The long gunners really need the full unit and the UA to be worth their points I think, although I haven't used them like that. Small units are terrible.

Sloan is good at killing but not all that survivable at a times is her downfall. But man she really makes defenders shine!

Let's see the sentinel is really... I mean I know where it is useful and amazing with Kaye but you have to use it in a specific manner and it requires you to be far closer to the enemy than I feel you should be with Kraye so I dont often use it anymore unless I have the points.

Oh and since you mentioned trenchers you automatically have to put the grenadier on that list

Also you forgot the over costed and silly triumph
