Rogue is melee which isn’t as desired compared to range and melee slots are limited. On the other hand, I think mage is oversaturated so more competition for spots within the class in groups.
Why not both?
Eh, no time really. Plus, I like the idea of being one toon…
Other classes can bring Lust as well though.
Shroud is only really going to be more useful than invisibility potions if your groups are doing prideful skips, if not invisi pot brings about the same utility (although being a bit more costly long term)
Also probably important to note as Mage you will most likely be expected to play Fire, which really requires a bit of knowledge to play effectively since most of your worth is within Combustion, as well as your group really playing around the fact you are a Fire Mage and have those big burst windows.
