Aserai was envisioned to be a fast faction that would use fast moving tactics agaist their enemies, their units (guard,skirmish/tribal would move around the battlefield engaging in small fights and harrasing the enemy with javelins and other throwables, but the thing is... the skirmish unit never worked properly, the guards got their throwables removed and the tribals are just slow AF and can't win 1v1 fight against any other heavy inf unit... So we got a problem here, all their inf is weak compared to the other factions, they don't have any type of advantage...
And the archers are just bad.. they don't have the range like the vlandia crossbows, or the accuracy like battania...
The other faction that got nerfed to hell was the Empire but yes Aserai has been in the **** tier since the beta....
And to show how much the Devs care about the Aserai just look at the latest costumization update... see the amount of armour the player can unlock with Aserai, and then compare it with Vlandia/Sturgia/Battania... that's how much love they give to Aserai... (khuzait is almost on the same boat in terms of costomization tho)
That's how I also always percieved them. Kinda like guirella soldiers. Many, lightly armed and armored, fast units. Using hit and run, kiting and ambushes to win the day.
In order for any of these strategies to work the opponent have to actively let you do it. The moment they have had enough of your tomfoolery and presses f1-f3 the game is over. Aserai can't run away. They can't win in melee or range. Tribals even loses to arbalest crossbowmen in melee if their numbers are equal.
The easy way to buff them would be to give them arms and amror on par with the rest of the cultures. This however might make them lose their intended flavour. The proper fixes (apart from buffing runspeed) actually have to adress fundamental flaws in the AI and the command system. Primaraly skirmisher AI needs fixing. Currently they are so dysfunctional that I belive the AI suffers from several bugs. They can hardly hit anything, they swivel around when picking a target, and they take forever to trow.
Also we need to be given a proper "flee" command. Where they won't engage with enemies that are still 10 meters away. Sometimes you could actually outrun the enemy, but the AI ignore your command to run and instead suicide in a sea of varyags. This not only hurts Aserai, but captain mode as a whole. Several maps currently has no other viable strat, but to go all inf and rush; the winner is the team with the better faction. Letting players disengage from fights would make the mode feel more strategic and less random.
