So here's a review of melee classes for you

Warrior is unplayable if you're not constantly in a group with people or twinked up the ass. If you're not willing to go through the grueling torture of leveling it to 60 (because it's only viable as a raid tank compared to other classes for its disciplines, for low level content an SK or pally will tank better, and for dps you'd rather be a monk or rogue) then I definitely don't suggest it.

Shadow Knight is a great class. Good at fear kiting which makes it very viable for leveling solo. Also very good at tanking, but you'll be hated almost everywhere. Don't recommend it if you're still new and exploring the world.

Paladin is the more "social" choice. Can't solo very well so you'll have to rely on being the group tank most of the time to get anywhere. Otherwise very well rounded.

Rangers and Monks can technically tank but their main job is to pull and do melee. The first performs better in outdoor zones and the latter is acceptable everywhere. They can solo very well and fit snugly in a group. Pretty fun classes. Avoid Iksar if you're starting out.

Rogues do good dps but only if they're standing behind their target which is impossible when soloing. If you won't be grouping with a tank then avoid this class too.

Concerning clickies:

"Clickies" are weapons or armor that cast a spell when you click them. They don't serve to make a class more engaging because they're just pieces of gear and not a mechanic or a part of any class. But they're tremendously helpful to help fill gaps that classes lack, for example a cloak might give a non-caster class the ability to levitate. A ring might let you go invisible. A pair of boots might make you run very fast. You can imagine they would be very useful for a class like the warrior or monk that has no utility spells and can only auto attack.

They tend to be abhorrently expensive because they're rare drops from powerful enemies most of the time so don't rely on having them.
