Before Orcs and Goblins had the advantage with the charge rules of attacking first due to the Waagh turn. Now they only get +1 Combat Resolution. With our low initiative I think this makes Orcs and Goblins worse.
we'll still have the waagh spell :P (+isn't there a strike first reroll to hit one as well? -- maybe they'll get even better now :D)
& on the other hand know your I values
(not meant insulting as personally I need some experience with that as well),
- you'll always be striking before certain monsters :P, vampire core troops, some warmachine hunters, tomb kings, dwarves, lots of lizardmen, ... and on same par with a lot of others...
another advantage of the waagh still remains,-- quicker in combat=less shooting to endure,
(ps I currently play without warmachines and fast cav; so for me this is an issue)
