God of war is just as rare to be fair I just think maybe you tend to notice it more because of the all red? Even so I've only seen god of war on about 4/5 people in the tower and I've probably seen substance and Arctic about the same, only seen the other like once or twice though. I got god of war about a month ago and got arctic about 2 months ago but scrapped it because I didn't like it on my titan and I didn't realise it was rare. IMO most shaders really do suck on the titan... The only one I really like to rock is thunderdevil. God of war is awesome though with the right armour, with CE armour you look like a lobster
