In response to the cannon Debacle.
I led the 8th on a random Siege event, and we were assigned to artillery. It was a custom map with only mortars. Now, I'll fool around with the mortars and stuff in my downtime, but I didn't have too much experience.
Now there were these trenches, and there were about 3 enemy regiments in them. I carefully aimed my shot with the mortar, hoping it would hit inside the trench. Now remember, this was about 4-5 shots after my first. It took a while to gauge this distance. I fired, and a few seconds later, a giant wall of death courtesy of me. 9 kills in all with that one shot. Now it had taken a while to get that shot PERFECTLY. And there was only about a 2 man width to the Trenches too.
Now, I was on the 8th server one day, and we had a few pubs on. I went Arty and switched the map to a Battlegrounds 2 one, the farm one. So I took up position on my cannon, loaded it. All that Jazz. So then I fire, and hit the other cannoner from across the map. That took one too few aimings to hit.
So in my opinion
Mortars - Pretty good as of now. Kinda difficult to aim, but rewarding when a direct hit is made.
Cannons - A little TOO noob friendly, not that having it friendly for the newer people is a bad thing, but when it gets too bad, then it's an issue.
Howitzers - Same boat as mortars for me, at least from my experience.
