Tactics
Decent. All healing and defensive skills are good enough and some are even interesting to use (Steady Stance, Soldier's Stance, Soldier's Strike, Victory is Mine!).
Beast Mastery
Good. Rampage as One and Edge of Extinction are probably the most popular skills, but I also like Heal as One, Call of Protection, Otyugh's Cry, Run As One, Feral Aggression, Enraged Lunge (in PvP, it's always funny when people lose 100-150 health and don't notice that it came from a little rat; since it doesn't show up in the damage screen

Illusion Magic
Kinda Bad. Other than Signet of Illusions, Wandering Eye, and Clumsiness, most skills are pretty useless compared to skills from other professions. Illusionary Weaponry still has sucky DPS... but I guess Arcane Conundrum and Air of Disenchantment may be useful in some cases. But, overall, it's still "meh".
Water Magic
Decent. Generally, this is only useful against fiery creatures (Winter is a pain to use and can be killed too easily) but it does have a few interesting skills like Blurred Vision, Deep Freeze, Maelstrom, Rust, Water Trident, and Ward Against Harm.
Air Magic
Bad. All of the skills, except Blinding Surge, suck against foes from HM or Elite Areas since Discord/Necrosis does more DPS and the Curses line has better skills to spread weakness and cracked armor.
Communing
Decent. Anguish, Pain and Shadowsong are good DPS spirits with some help from Signet of Ghostly Might. Shelter, Union, and Weapon of Quickening are also quite fun to use.
Motivation
Almost Decent. The party healing is still pretty bad but it has good condition removal skills and I still like Mending Refrain for its ease of use.
Oh, and I think scythes are fine the way they are since Dervishes have the Avatar Forms. I'm not going to bother explaining why Hammer Mastery is good enough already >_>
So the only attributes, that I think need to be buffed, are Illusion Magic, Air Magic, and Motivation.
