I'm sure they'll update the stats later. But at end game the deciding factor is abilities much more then the raw boost. +-50 doesnt make too much of a difference when you have 3K attack boost. Only really plays in at high attrition, but at that point, your fighting slow anyways...
Looking at the abilities, I think its gonna be ranged being primary troop again
Ranged = Blast
Arty = Mortar
Heavy = Stealth
Fast = Flying
Light = Force Field
It appears they are keeping the heavies with the trash range, which'll mean offensively they wont be worth anything beyond maybe some niche cases like DAs. The fast with flying will probably be decent. They likely will be able to knock out ranged/light/arty/other flyers pretty easily, but might struggle a bit against the heavies. Arty would be good in theory just like the OF turtle, but once again we're gonna see them flop due to inability to touch flyers. Once again, might be useful in DAs, doubt much more then that. Force field is mostly meaningless, if it impacts the fight it means you arent at low attrition / need bigger boosts. Ranged will likely be the most decent troop. Probably roughly comparable to Grenadiers. Id imagine at low attrition they might even do slightly better seeing there isnt any reactive armour. They'll be able to kill heavies/lights with easy most likely. Flyers and artillery is gonna be dependent on turn order. If they move after and arty cant hit them on first turn in particular they will likely be decent against them. However if arty can hit them first, then I'd imagine any fighting involving artillery is gonna be rather bloody...
