Most everyone has already posted what I want to see changed, the only thing I have to add is that I personally would like to see dreadnoughts benefit from the invulnerable save improvement when running a pure detachment. That seems like the custodes equivalent to chapter tactics, and other chapter tactics cover infantry, bikes, and dreads.
I agree, would happily see the telemon go to a 5++ base and then improve to a 4++ in a pure Custodes detachment an the Contemptors also, and I'd also like to see them all get Ob Sec, appreciate that 4++ Contemptors may require a slight points increase, and I already mentioned above they should go back to 12 wounds, the marine relic contemptor is 12, how are Custodes ones not relics exactly.
Actually, Telemon got a base 4++ with the rule
Reinforced Atomantic Shielding: This model has a 4+ invulnerable save.
so basically you already have it.
