Hi Kyrt and thanks for the thoughts
I agree the Shadowseer takes some getting used to. I find it easiest to lay the enthralled units on their side, or even to remove them temporarily (which is the end result anyway).
Scout was added to allow the Shadowseer to move further away from his friends, which i agree is a sort of 'sticking plaster' but seems necessary to clarify the situation in the assault (otherwise we are measuring millimetres which is fiddly).
And the Shadowseer stats have been revised to make him a character for 50 points. He has a FF attack which means he can still fight in formations other than the Mimes (which I agree is a slight drawback, though infiltrate does allow you to position him against 2x units allowing him to attack the 2nd if he only enthralls one of them). He also has Farsight, enabling the 2nd retain if necessary (though he cannot summon the Avatar; only Gardian Farseers do this). In Mimes he is most useful in excluding dangerous enemy units and in reducing the enemy formation numbers, though I agree it is a trade-off
Like I said in the report, the Shadowseer is a bit of a double edged weapon in that he brings out benefits and penalties, so needs to be handled carefully
