'allo there dps, fine day we're having. Question for ya!

Personally, I don't care if the tank marks targets or not. I have a /assist macro, so I'm always attacking what the tank is. It's nice when they mark a whole group so I know what they intend to fight 2nd and 3rd etc, but its not required. I don't know what the difficulty is. /assist <2>...

Yes, you can use assist to target the tank's target but that target isn't necessarily the one that should be focused on. Like I mentioned above, some tanks frequently switch back and forth between targets. If one is marked as "1" then I know that's the mob that should die first and if the tank switches to another one temporarily I know that he'll eventually go back to "1". I can just focus on that target instead of constantly hitting assist to see which one he's attacking all the time. It may be easy for a MNK to swtich targets but SMNs take time to cast spells (about 7 secs for the main dots).

For those tanks that do mark their targets, kudos to you.
