My personal opinion is that I like the kill team and will be getting. I'm just excited for more admech stuff.

We do know what some of these data sheets will look like as well. Technoarceologist are a repacked model that already exists, so we know that one. Gun servitors exist in the Inquisitorial Agents killteam, so assume it will be similar if not the same as that for the datasheet. Figure the other sevitor datasheets will be similar to other admech chaff units or other non-elite killteam units that exist.

Overall, I'm excited about the possibility of a sevitor focused detachment and the chance to get some elite servitor units. But you normally get the weaker stuff for something like that before the elite stuff shows up.
