For a lot of the choices in our codex, this is mitigated by being very effective at what they do. An example is the Predator. It puts out a ton of firepower for the price. The same with Ven Dreadnoughts. They validate their points by being great sources of survivable fire support. So they aren't really my problem. Its the transports. Do you think transports pull their weight?
So lets look at the rhino. What do we get for those 72 points? You get a transport capability of 10. The ability to bumber car assault. You also get some line of sight blocking from them, but that is about it. Not really worth the points, when we are so strapped for points elsewhere. What about Razorbacks? At least with these, we get some guns with it. But even the most basic version is 87 points and you're looking at twin heavy bolters. If you go for more powerful weaponry, you pay a premium. Is it worth it? I don't think it necessarily is. In my list building, I've almost started to consider transports a tax that isn't needed in lists. Just think about it: I lose a bit of mobility, but I gain a ton of points that might be more beneficial to my army. More bodies, more firepower, additional weaponry. A ton of things. What do you think? Are transports obsolete?
