welcome to L2!!
TKs are pretty boring, every time i tried lvling one, i rerolled :p but you can choose whatever class you want, it's all about preferences.
go onto the Gustin server and pm me (Gharik) ingame when it finishes downloading :p i may help ya out ^^
if you choose a DPS class go..........Gladiator or any dagger class
but I was looking over temple knights (i always like to tank)
they in demand or am i just better off choosing a dps class?
Some days it seems like *everyone* is better off choosing a DD class. :(
A Temple Knight however, is the antithesis of a DD. Lowest STR, Lowest Damage of all tanks, some might even go so far as to say their dps is roughly on par with a Dwarf....their main 'ability' seems to be mostly having the highest shield block rate of all the tanks. TK's have histroically been one of the most 'ignored' classes by the developers balance/nerf bat. They have gotten a little bit more love with C5/Interlude though.
Anyhow, there really is no 'demand' for a Temple Knight....but then again demand for *any* tank is almost non-existent. Offense is currently king in Lineage 2, and it often seems like Defense is only there to make you die slightly slower and with as much despair as possible.
BUT! Who knows, the next Major update could change things radically. (Interlude is a minor update, not a Major one.) If the new Primitive Island added in Interlude is a indication of things to come, the devs next major changes could make them necessary again. As it stands now, tanks are only really needed for raids (and you only really need 1-2 for most, and raid drops got nerfed enough that few are considered 'worth' doing.) and a couple of the 'tough' mob locations that few people go to anymore since they are soloing their archers and nukers with their buffboxes in the 'easy' spots.
In general, Light Elves receive very little love from Lineage 2. Defensive classes have it even worse. A well-buffed dagger user can out-tank a tank in most situations except for large raids, so for most of your career you'll be considered as not really usefull. Until that one time your clan wants to do raids and realize they need you but they forgot to help you level up since you'd have slown down their exp rate.
Thalenduros pretty much covered everything I wanted to say except...
First off, tanks dont ever loose to daggers unless the dagger lands a lethal.
You should change that to "special", as even sub-40 tanks lose to daggers fairly frequently. Daggers land their specials often enough, and have such incredible DPS, that they can often simply slice-and-dice a comparable tank to ribbons within a short period of time... not to mention that the 25% land rate, from the front, of the various "Blow" skills is still a lot better than most tanks' complete lack of comparable skills.
