Here has been a question of mine for a while…
When you make a character, do you find it to be better to choose a chapter that is redundant with your specialty or complimentary?
For example: Iron Hands Techmarine. The chapter and specialty clearly overlap in many areas. One might say that one of the benefits of choosing Iron Hands as a chapter for a different specialty is the benefits they get in having Tech-Use available and for cheap. Also, The Flesh is Weak is a really great talent to get and is relatively cheap for Iron Hands. Assault marines can really benefit from The Flesh is Weak. On the other hand, The Flesh is Weak is cheaper for Iron Hands than it is for the Techmarine so and Iron Hands Techmarine would be able to get many talents for cheaper and be able to spend more on other upgrades. For Iron Hands, The Flesh is Weak is 500 for levels 1, 2, and 3. That's much cheaper than the Techmarine specialty offers it and you cannot get that high in that talent until you are Rank 5. Techmarines have to spend 2,600xp and need to be Rank5 to have it that high and Iron Hands, Techmarine or not, can have it at Rank 1 for 1,500xp.
So, which side do you fall upon?
