Need help between war and pld

[TallonOverworld]

Keep in mind that no matter which of the one you choose, both are able to tank successfully in both end-game and early game content.
Although, paladin has a small issue with aggro in levels ~30-40 (where you get your tank stance, warrior gets it at 30), you can overcome it with a bit more careful play. On the other hand, warrior has hardly any problems with aggro 1-60 provided you "know" how to tank and keep enemies on you constantly.
The real game, however, begins when you hit 60. Paladin, as it is mentioned above, is a straightforward TANK meaning you don't deal damage but you can sustain the highest of hits with many defensive abilities + ability to heal yourself.For warrior,which is my main, things become a bit more fun and challenging. Warrior gets a dps stance + skills for it (a HARD hitting single target, and a decent aoe). Efficient warriors manage to switch between stances mid-fight (what we call stance dance) in order to not only tank but to achieve high dps as well. However, if you don't know how to handle this properly, it can be fatal.
Regarding the tank aspect, warrior has the highest HP pool of all classes + mitigation skills + beastly self-healing ability. Im sure you might have heard of cases where warriors are able to solo dungeon bosses or even alliance-raid bosses when everyone else is dead.
To sum up, paladin is easier to play than warrior only because it misses the dps aspect and requires somewhat less focus on your character (of course this is not the case in savage content). Warrior on the other hand, is much more fun to play but it needs you to constantly keep an eye on your stance (if you decide to switch mid-fight) and also the damage you are taking. Both classes got their pros/cons and we must not forget the skill gap between players as well.
