Ok, I've got some complaints about Sharwa Castle. During a siege, it's simply waaaaay too friendly to the defending army. Attacking troops have to run a great distance to even reach the castle while the defending army's troops are in the mix in a matter of seconds.
Let's have a look at a few screen shots;
First we have the siege tower's starting point. Note how far away from the castle it is:
Here's another shot of the starting point, with my character standing directly in front of the siege tower:
Here's a shot of roughly eight or more minutes later
when the tower finally arrives at the castle wall. Please note I've already lost 36 friendly troops:
Finally, here's a shot of me looking back at where my troops are spawning from. Please note the extreme distance they've got to run to get in the fray:
I have to admit, this siege was extremely frustrating when I was doing it earlier. Please look into having the siege tower and reinforcements for the attacking group spawn closer to the actual castle.
