Yeah I know Im annoying, one more question...
 

Right now I am running a 3-4-3 with all my back guys playing defensive, and my forwards playing offensive...for a team that just started and low skill is there a better formation or is this good?

No such thing as annoying... better safe then sorry when you first start HT. So many people screw up they're team when they first start because they're not sure what to do and don't ask any questions.

Now about your question.... If your training scoring then yes a 3-4-3 with 3 inner midfielders, 1 winger, forwards offensive and your wingbacks defensive is the way to go. Defensive forwards contribute to your midfield some at the expense of your attack rating, but only if they have good playmaking. I find playing a defensive forward is a waste so i won't even worry about them.

I run a 3-4-3 and train playmaking, nothing wrong with that combo either.

Formations depend heavily on what you're training. Playmaking trainers are tied to a 3-5-2 normally or a 4-5-1 when they want to turtle (unless they want to sacrifice a half training slot), scoring trainers to a 3-4-3, and winger trainers to a two-wing formation which likely means a 3-5-2 except when they want to turtle in a 4-5-1, defense trainers to a four- or five-defender formation.

Keeper trainers are not subject to such restrictions -- there, the formation choice is probably best driven by personnel. If your wingers are stronger, play 3-5-2, if you've got three good forwards, play 3-4-3. Either formation can be successful.

What do y'all mean by 'offensive' forwards? I don't have that option...

unless you mean forwards that keep slinging insults at the opposing goalie...

The 'Normal' for forwards is offensive, according to the rules, I guess that is what they mean.

...and also on the strengths and weaknesses of your opponent. Generally speaking, it could be better to play a 3-4-3 against a defender trainer, but maybe 3-5-2 against a team with a better midfield. I have a friend that is a goalie trainer and he plays a 5-3-2 CA against the top teams in his series, and a 3-4-3 against the lower teams. Goalie training leads to the most varied strategic choices.

If you've got the personnel to play both formations well, then you can afford to make the decision based on your opponent. I don't feel I have that luxury right now, so after a long time as a 3-5-2 team, I've been running a 3-4-3 for much of the current season.
