My opinion is worth nothing but its so dissapointing to see Memnon be a permanent horde. I was so excited to lead an army with Egyptian and Nubian influences but its trapped behind the whack-a-mole endless tedium of a permanent horde. I thought the beastmen rework signalled the end of this style.
The worst part is unlike the Amazons we dont have a choice of normal faction and horde faction for this culture. Additionally you can probably forget seeing Memnon AI showing up in your games as he will likely get squashed like Penthislea in the opening stages of the game.
It feels like also a disservice to his character as now Memon is being reduced to a savage despoiler destroying everything he comes across while the new Thracian character seems to be a normal empire builder.
