I recommend the following skill point allocations for level 40 players
Essential Skills
Combat 3 -- Simply a must
Taunt 3 -- Great to maximize your kills
Trodent Doctrine 3 -- Essential for hunting
Cleave 3 -- Also essential for hunting
Dragon Master 2 -- 20 Extra HP invaluable for non warriors and warriors alike
Very Important Skills
Shield Charge 3 -- Great for hunting
Serenity 3 -- Saves those valuable seconds, good for groups
Blacksmithing 3 -- Save gold and halvar keeping your weapons in trim
Scavenge 3 -- Extra gold especially from silkies
Important Skills
Troll lore 2 -- if you chop trees a lot
Aquarian 1 -- for pearls and whirlpools if you water hunt
Monolith 3 -- My absolute favourite if you can get it unlocked
Warden 3 -- Great in a group
Archery 1 -- In case you need to use a bow
Unessential skills
Hunter's eye -- yes you can live without it and it hinders your silkie runs
All crafting -- get them with your gold and connections
Cartography -- Use gold
These make up my rough pyramid of skills. Different classes will have different priorities, but I'm basing mine on Legion. Militia will want archery and Ninja will want Oiyoi, for example. But I think the mix above is a great template.
