Random questions regarding game mechanics

LOL at no 4. Not played qot so I've not heard that yet!

The light bolt is a pretty picture the towers hit you individually. 

War score accumulates by controlling the Flags.

1. Warscore comes directly from flag control. The more flags the faster it goes.

2. No idea, honestly the nightmare is rather easy since it doesn't get to "cheat". I think maybe the harder ones start teleporting out of combat.

3. I'm pretty sure its enhanced damage. Tower rook can also mount one on his shoulder to effective extended the range as well.

4. lol, if you click on oak enough he says "My.....armour......itches" ^^ 

3: just a pretty animation .

4: drink coffee while respawning or in the lobby

3: it has already been posted here very detailed in some thread:

let's say you have two towers and one enemy. the enemy stands 10m away from tower1 and 20m from tower2. let's assume       the tower range would be 10m. the first tower is able to hit the enemy directly, the second is not. but in fact tower1 is in range of tower2, so it uses the range of tower1, shooting through it at the enemy.

so linking towers does not precisely increase damage but in fact increase range.

i read this somewhere here in the forum and observed towers after that and i could see that one tower would shoot faster if he's linked with others than if he's alone, so i guess it's true.

Nope, tower links don't increase range. Just pretty animation. Not only asked about it, I've read it a couple of times, even tested it myself eventually.

About 2, they become a bit smarter.  I never see easy comps teleport, unlike hard ones, and normal never dodge my Rook's hammer, unlike hard ones.

1) What exactly are the things that contribute to War Score and the most significant way to accelerate it?
Miyamiya is correct, flag control is directly responsible for your War Score speed.

2) What are all the differences that occur between "Easy", "Normal", "Hard" and "Nightmare" AI opponents?
The main difference is item and abilitie usage - the tactics they employ are identical from what I can see. The more difficult the setting, the more complex ability combos they will use. An opponent on Nightmare also received additional benefits - namely increased XP gain and regenration, from what I can tell. No offical word on this as far as I know.

3) What's up with that graphic of an electrical bolt traveling through a series of towers? Is this just pretty pictures or does it indicate enhanced damage or distance or some other meaningful result?
This is purely visual I'm afraid, from a numbers stand point it changes nothing.

4) Is there any way to stop the coffee from going out my nose whenever Queen of Thorns says "My eyes ... are up here."?
I find a clothes peg on the nose does the trick, although it does hurt

Ok so it appears that flag control is the only factor that anyone's identified as contributing to War Score. That was certainly my assumption and what I observed. I was just wondering if there was anything else that anyone was aware of that also played a part.

Mixed opinions on question 2. Miyamiya, what makes you state that the computer "doesn't get to cheat"? Is that a statement from the devs? Cheating AI's are notorious shortcuts to diverse "difficulty" modes. Has GPG explicitly taken a different approach? If so, I'm impressed, but I'm skeptical. Some of you have noticed different behaviors (like the suggestion that Easy AI doesn't teleport as often). Personally, I think the AI over-teleports. How many times have you played the AI and waited for that blue flash indicating an impending teleport and then killed them with a well-timed interrupt?

More mixed opinions on question 3. Some indicate enhanced damage, others indicate enhanced range, but most say pretty pictures only. Guess this one will require more testing. It's not a big deal, but I assumed when I first saw these bolts that they indicated some kind of grid for transfering damage from back towers to front line towers. That's a significant amount of code to put in just to add pretty pictures, and it's kind of a neat idea to employ a tower "network" as a means of delivering some kind of benefit. Pretty pictures would be ... disappointing.

I said I was pretty sure about the towers, but now I'm not so sure. ^^

Also I've never seen instances where the computer cheats, and it doesn't feel like they have a significant gold/xp advantage to compensate. I haven't tested it, but it would also make sense with the multiplayer rating system using AI that they wouldn't allow it to.

And about the teleport, I agree completely, as Sedna its a huge advantage to know that they will always try to teleport or pot out of combat. The hilarious side effect is when new players try to emulate this strategy against humans with disasterous results lol.
