EMIC help...

Emic is not about defending the wall, it is about camping the 4 spawns there are 2 main ones on the extreme right, one top and one bottom. Solo emic is not easy you need good eco speed and good gear/advisors. There are a couple main tips:

1) You MUST get a sizable force on the 2 main spawns before wave 10 or you will lose (this is the first siege wave and if you allow waves to fully spawn its over)

2) Use melee units with decent dmg like cavalry or strong infantry

3) Make fake walls in front of the premade wall (a fake wall is just a wall segment on its own, it soaks but damage and attracts enemy aggro but because it is not connected to anything only that segment takes dmg, make like 20 of these in front of the premade wall)

4) Towers should be made a bit early behind the premade wall, you should have around 18-20 total including the starting ones. These combined with the fake walls in front will buy you enough time that you can focus on your eco and get army out.

5) buy upgrades as you eco because you must get a decent sized force to the spawns before wave 10, i cannot stress enough how important this is.

6) you do not need as many units on the side spawns as the main spawn because the side spawn only rarely sends siege

7) Once you have armies at spawns you should make towers around those areas to provide extra damage. Last 8 waves are especially strong

8) last and most important tip. Play coop, it is much easier.

 

they do spawn siege on wave 31 but otherwise never.

 

If you want to solo EMIC, I would suggest Rome with Crassus advisor - The huge boost of gold and increased pop means that you can have a full 220 legionaries out roughly wave 20, and thus be safe.
With that said, EMIC is one of the hardest quests to solo currently especially after it got shortened.

 

I recommend you to use hotkeys for building placements and unit production.
Change hotkeys to be easier to use like:
QWE
ASD
Q First unit like spearman
W Second Unit like Hypaspist

Q for Barracks on every civ
A for Archery
S for Stables

Write the Hotkeys down on a paper. Dont click on the pictures anymore. Use the Hotykey whatever long it takes.

Bulk up the main unit you need with good gear (ramses gloves etc)

I use idle vill hotkey at spacebar and check it constantly.

I think its only possible to find them one by one. But you can double click and add other stables to the selection by holding shift i think up to 100 stables and produce the strg +1 etc group

 

I like to bind "select all units of the same type" and just click one ie:barrack or click my current control group for it and then select all of the same type then rebind.
There's probably some other ways, but "all of the same type" just works well with so many things.
