I haven't played 40k in a pretty long time (mostly 3rd edition) so combing back now there's obviously been some changes - at least I hope they are changes and I haven't just been wrong for years.
Anyway, I was hoping you kind folks could help me understand a few things, both dealing with the RAW and with the why behind them. So, there have been a lot of changes to the game but oddly a lot of them aren't really changes just new USRs and army books and such and none of that I really have a problem with. But there are some things, the basic things really that I took for granted for years that have changed do have me a bit confused.
The first thing I noticed was blast weapons. Now, I could swear that back when I last played that you rolled to hit, then if you missed they scattered. I looked pretty hard and I don't really know for sure but it seems that now you don't roll to hit with blast weapons, just to scatter, is that right? I ask because that seems really REALLY weird from my point of view, especially with how common super heavy vehicles and super big guns are now, it feels some combination of busted over powered and really really nerfed. Weapons with small blasts it would seem are now much worse than before, with a much lower chance of getting multiple hits since you no longer get to place the template to your advantage, it just goes where it scatters. On the other hand large blasts seem to be a lot more powerful now, especially against vehicles - There's a good number of vehicles where you could reasonably roll a 12 on the scatter distance and still hit it with the template, and (again correct me if I'm wrong) no longer do you need to hit a vehicle with the hole in the template to get max strength. Is all of that correct? Are big template guns now really THAT much better than say a lascannon or multimelta at killing vehicles? Is this stuff a response to the arrival of hull points so that the game is now more about trading off hull points than just waiting for one of you to get a lucky hit?
Slightly more generally - I didn't look too hard in the book, but since I'm typing I may as well ask - How many saves can one unit take against each attack now? As I recall you used to only get to roll one save, and only one thing (Feel No Pain) screwed with that after the fact. I don't think that's really changes, but then when people talk about the game they list off like four or five different saves that a character might have and I just wanted to feel a bit better informed how it all interacts. Do you still only get to roll one type of save per incoming attack?
Thanks guys
