I am level 5 with my whole group: Main (Rogue), Shadowheart (Cleric), Gale (Sorc), Lae'zel (Fighter).
I want to fight melee with my rogue, because this is my pure understanding of that class.
Maybe, I am playing it wrong, but after my initial sneak attack it feels pretty dumb to stay around and just hit with a normal attack next round - it feels pretty unsatisfying to be honest.
In my opinion, ranged damage / ranged enemies is pretty strong - currently, I am looking for some protection against ranged damage, because most of the combat (balanced difficulty) against my group has devastating outcomes, when 3-4 ranged enemies are taking actions (just want to mention the Duergar Ship Battle). I had to reload this fight 7-8 times to defeat all the dwarfs.

PS: Sorry, I'm from Germany. My game language is German, so my text could contain some wrong descriptions.
