The team spawns/flag cap areas favor one side so much it is ridiculous.
No I actually think it is pretty fair on CTF. One side has more cover for defenders, which also makes it easier for the enemy to sneak up, grab the flag, and use that same cover. Other side has little cover which makes it harder for the enemy to get to the flag. If you are far better at one tactic (using cover or out-shooting), you may think it is unfair, but I may disagree.
