Hey there! (Im starting to feel like spammer with all these questions..) sylvaneth forests are in warscroll list so can I deploy them like any other units with every forest counted as 1 additional warscroll ?

One more question - do I roll for sylvaneth forests features like if it was a normal terrain? (Cursed, blessed, etc..)

You place it just like other scenery. You don't roll for its rules, the warscroll rules replaces that.

Don't worry about asking lots of questions. In general, for every person asking a question there are a dozen wondering about the same thing but not bothering to ask.

As for the answer, Chracian has it covered. It's treated like scenery but then with all rules included in the warscroll instead of rolling on the scenery table.
