>>124756343Britonic Celtic culture was older and less developed than the continental culture and was hilariously diverse in how weird it fought wars.
For example, the Gauls traditionally used tactics like the Romans, Large shield infantry units with swords, Skirmishers with Arrows and Javalins.
Britonic Celts still used Champions, but if the opposing side did not have a Champion or a full scale battle was needed, they rolled up half naked with a loose shield wall to distract you while the Clan Elite rode around the backline in Heavy Chariots to hack apart your weak flanks.
Caesar was utterly dumbfounded by the idea of using Chariots as Melee Infantry transports, and it worked so well Caesars first invasion of Britain utterly failed.
As for the Firbolg business, I don't think it works because it just turns them into Pastel coloured dopy half-giants instead of the Celtic "Good" Giants they're supposed to be. The cow theme resonated with Twitter and tumblr artists who made them look gay as fuck, people who knew about Firbolgs beforehand like myself fucking hate his shitty outlook.
For the Record, Firbolg were one of the few races of Giants who were actually friendly, so reducing them to a meme race instead of leaning into the giantkin is pretty annoying.
