Because of you lose wayy too much is more Skill Issue TBH, also only the Sicilians are kind of bad now, but Burgundians are still absurd on arena 1v1 and TGs.
This reminds me of the situation in StarCraft 2, when fans of each race complain that the opposing race is stronger and generally OP. Well, if this is the case, then change your race and play for those who are OP.
I just totally wrecked an AI Georgians player the other day on an open map as the Burgundians. They’re actually pretty good if you know how to play them.
