I consider the changes "notable" certainly people will be getting out the pliers to redo vehicle weapon configurations, many existing armies will just not be the same.
I think a big big big change is that gunlines are going to be trickier. Or at least will have to move up. The infiltrate from the edge thing means that against such armies that back foot is a killzone. Especially since many infiltrators have move through cover. Deepstrike sounds a little safer, which will also make life harder for gunlines.
As for my mobile Eldar it really remains to be seen. Lots of stuff will take a while to feel out. Like harlies.
Minus Rending now worse.
Plus Sounds like we'll be able to stick them in a wave serpent now. At least some guardians wave serpent.
And Falcons
minus Don't get the skimmer moving fast rule, sounds like may not get to fire all weapons and get the cover save
Plus Is the cover save option, and the armor table sounds less deadly, hence the reroll will still be important
And so on.
