Comparing Diablo 3's skill system to Guild Wars' is like saying that since Call of Duty involves first person shooting it's effectively as good as doom which also involves first person shooting. Get the fuck out dumbfucks.
No, that is not what anyone is saying and furthermore that is not a valid comparison at all.
Diablo 3's skill system is like a more basic version of the GW system. No, it's not as good or as flexible, and yes, GW's system is much more complex and intertwined. All I'm saying is that it's similar in the way it works; you get all skills and it's up to you to decide which you use. As I said before, D3 would be much more fun and flexible if you could dual class like GW lets you.
I agree with Cowboy Moment that the skill system is probably just going to be a clusterfuck for standard co-op. I'm thinking more in terms of doing hardcore characters and trying to come up with viable builds that can survive various areas. The softcore game, especially now that you don't lose your corpse and spawn at checkpoints, is basically just throwing cool abilities at monsters. It's no wonder they didn't allow 8 player co-op or it would just look like a rainbow threw up all over the screen.
Wow, if you count every D3 skill 6 times it has more skills! Amazing!
Furthermore, I've never heard complaints about the number of D2 skills, only that 80% of them were far too weak to build for the last difficulty. This will of course happen again because Blizzard has proven that their ability to balance their games in the distant past was a fluke.
Even if you count single skills and not the rune modifications it still has more skills. The point is that instead of Diablo 2 where adding a skill point to a skill makes it do X more damage, adding a rune to a skill in Diablo 3 changes the effect of the skill, sometimes dramatically.
There are hundreds of combinations, but one example is modifying witch doctor summons where you can give them a health leeching attack, an elemental attack, "light them on fire" which gives them an aura that does damage to all enemies around them, etc.
And the way the skill system is setup, I believe the goal is to keep most skills viable for a long time. It probably won't be balanced well at first, but that's supposed to be the goal, anyway.
By "like" you mean the exact opposite, right? D1 forced you to discover spells randomly and if you didn't find Heal until the level before Diablo then you had to deal with it.
I said it's more like D1 than D2, not that it is identical to D1, jesus christ. It's more similar to D1 than D2 in that you have access to all the skills your character has, not determined by a skill tree.
