I'm a long time wargamer and a BT/DG player for about 10 years and no I'm not a grumpy old man complaining about 2ed or rogue trader. But, I have put my BT on the back burner until GW works out their plans on Primaris marines as I find it is be a poor gamble investing in marines right now.
With my frustration at GW I wanted to get another army that would fall outside the Primaris issues. Custodes seem interesting as it would be an elite army being a small model count but most likely about the same monetary cost but I have two concerns.
First is there a better option for the Ven Dread then the really bad plain one GW makes. Can the FW Custode dread be converted with a ranged weapon?
Second looking at the stats via the index it looks like Custodes would have a very hard time on the table top. Ignoring stuff that is not released the index unit seems to be either two light on resilience and clearly not able to provide much ranged fire support. As someone that has not played them and only going on my years of wargaming they look like they could be very challenging. How are they doing on the table top?
PS: I do not like playing with jerk army lists but I also enjoy having good games. My favorite WFB army was Tomb Kings and I like Death Guard when they were very challenging back in 3.5.
