Wiki told me how to roll a Cleric

[Solist]

90% of people writing that have very little clue about the top end or elite of solo/duo play, endgame raid etc. Play what you love to look at. What you enjoy looking at is by far the most important thing.

Humans dont need an AoN to navigate kael like a gnome does
Humans get snare neck clicky and an extra clicky (deadeye helmet)

Gnomes can see through walls.
Gnomes have a pretty nice aggro clicky.

Both can wear robes which is excellent. Innoruuk human or bertox gnome are the only realistic choices from a minmax perspective. Human has more starting charisma.

Neither can hide (is not good now its not IVU too since 2012).
Hlflings can sneak. Sneak is nice for 1-2 random quests in the game, and sneaking past 2drakes in VP (hardly an issue).

So play what you love or you could argue the points for weeks and never make a decision because its all irrelevant really.
