Yep, thats true.
I usually play GW with a friend, and when we must face a boss whith we get killed many times, we always try new playstiles, other habilities and combinations and strategies to achieve our goal. I am not going to say the system they use is the worst, it has his advantages over other MMO because with it your character has your own playstile.
I dont say that system is the worst, but i dont like it at all

Its just... Maybe it is an obsession of mine, but i always compare MMO with theyr own reality, the "reality" the game offers to the user to play with, if i have a character awith some habilities, i like to play with them all, maybe i wont use all of them at the end but they are a part of my character, the character with i have played along the game.
Basically i think: "¿My character learned an hability but its like he forgets it if i dont take it to the hability bar...? weird" The truth is that I am more of interpretive forums and games such D&D and Vampire with theyr dice than MMO, maybe its because of that
Well, going back to the subject in this thread, yes, i like to have a large amount of skills to choose instead of only 5 or 6. In that way you can choose to select only a few of them to personalize your char in the way you want fight, or learn to use all of them in each moment to give them a good use in a fight.
