Arguably, goblins were a lot better in 8th edition than they are now.seems to me that we are still far from the days of 8th edition
Double doom diver, double rock lobber and 100 goblins with the spider banner for 100 poisoned shots per turn, and a few trolls and big bosses to mop up the survivors. That was a grand tournament-winning list.
Well when you see a pattern....It doesn't make sense to fear bad consequences
The thing is, I am actually more worried about the direction of goblins than the power level. Warcry, close combat hereditary spell, loss of shooting and decreasing book complexity all point in one direction: in order to fit orcs and goblins into one book, orcs and goblins will become more similar.
