The sidekeep flag on Helms Deep cannot be captured. It will tell you to capture the Wall flag first, even when it is already captured.
(This bug was known, but not reported on the forums)
The parry ability adds extra absorption hearts when triggered, but the amount of time those hearts last is the same amount of time for the cooldown of the ability.
This means that you can only damage someone with the parry ability if you deal the amount of absorption hearts + some more in the...
You can activate the horn of mordor with left clicking instead of right clicking. This makes you glow without there being a horn sound. I don't know if this is also the case with other horns where the user doesn't glow.
Add more information to the horns. Right now it just says which type of horn it is, but it should also say which potion effects it gives and for how long. And it should also tell what effects the user of the horn gets (example: glowing).
If you close the gate, and while it is closing hit it to break it, the gate becomes closed but also broken meaning you cant get through it anymore. This is at least the case for the ladder gates on helm's deep.
Flags on Minas Tirith are recappable. This shouldn't be the case, because it is very annoying to backtrack. The flags are very far away from each other.
With the Westfold Axeman, you get a shield which you can use shieldsbash, however, it has friendly fire and you are able to push your team members away with it. This should not be possible.
Mordor lobby: Contains a sign that switches you to the mordor team. It basically just teleports you to the lobby you are already at.
Gondor Lobby: The lobby does not have a sign to go to the spawn.
You are able to drop certain items, and some items can't be dropped. Armor for example cannot be dropped, but for some reason you are able to drop your weapon on the ground. You should not be able to do that.
You are able to take items out of flower pots and put them back in again. This doesn't matter a lot, since it all gets reset when the map is played again, but I am going to report it anyways.
When someone becomes a hero, you get a morale boost. However, when you restock at an ender chest, you lose the morale boost. This is probably also the case for cauldrons. And this probably also applies to all other effects.
On minas tirith, you are able to break the second gate before the flag before that is broken. That is likely also the case for the other gates. Gates shouldn't be able to be broken if the flag before that is not captured yet.
