I've been making example characters in RT, and just finished my first Exporator, and so I've been reviewing the things they can do, and seems to me that Mechadendrite Use is never going to pay off!
Each of the talents are expensive, and the Mechadendrite (which it seems you must acquire separately with PF) are week cheese, you’d better off with a swarm of survo-skulls or combat servitors, and concentrating on making you skill and other tech powers like Ferric Summons and the like then investing in Mechadendrite.
My issue with this is, in WH40K in the muti-Mechadendrite tech-priest is depicted so often it’s become iconic, but to make any tech-priest (DH or RT) that uses Mechadendrite is an inefficient use of xp.
Comments, am I missing something?
