Why and when is xbow better than an archer (Warden)?

[Swaliant]

-Crossbowmen have better armors and melee skill.
-Best character for peeking thanks to infinite draw, which is a huge advantage against ranged enemies.
-Massive damage, higher shot speed and range.
-Can knock down enemies even with a craftable crossbow.
-Accuracy higher than 100 is not just show, I know this from my own experience with my chosen marksman. I was on hard, grabbed Sharpthorn which has better accuracy(110?) than Elegant(99) and I really felt the difference.
-Not every map is suitable for kiting.
-Might even have higher dps if they have Ailadrodd.

Also it is really about personal choice, all classes have their advantages and disadvantages. They are not superior to each other, but rather different.

P.s. Melee is the best.
