I beat the entirety of Prophecies as a Ranger/Warrior using a Sword/Shield with nothing but henchmen. I didn’t find the game very difficult by the end because it’s not very difficult for me to look at a bunch of very similar skills and put together a build that works. You might doubt that claim, but then, I beat the entirety of Prophecies as a Ranger/Warrior using Sword/Shield with nothing but henchmen.
I found the game more challenging when I was fresh out of the searing, didn’t have a complete attack chain, didn’t have many defensive skills, and didn’t have the stats to make much out of them anyway. I had to learn how to command my henchmen to get things done as I myself was fairly weak. Now that I am a kitten Ranger/Assassin with a Death Blossom skill chain I can pretty much walk up to every encounter, AOE it to death, and then heal myself afterwards. My henchmen are there but I mostly just ignore them.
As far as “skill diversity” goes, there honestly isn’t that much of it. A lot of skills are so situational that you’d need a really specific party composition to make much use out of them, and since you’re usually dealing with only a passable AI you tend to stick to more general things. My strategy was to pick four attacks that had the least amount of conditional situations applied to them with good damage and put them on my skill bar. Then I picked some utilities that healed me, removed conditions, and let me just ignore 75% of everything for the next 12 seconds.
Game stopped being hard around Fisherman’s Haven because my build was more or less “done” by that point. I wasn’t learning any new skills that were useful. I wasn’t acquiring new armor that would make a difference, and the enemy AI wasn’t capable of becoming more complex. The vertical progression was “done” and so the game was quickly “done” after that. Enemies, mathematically, could not do more damage than they were doing in Hell’s Precipice without giving me more power, so that is where the game peaked.
Again, I don’t mean to turn this into “look at how good I am at GW1”, I mean to point out that I found the game challenging when I was fighting my way up the power chain in it. I felt a sense of progression as I emerged from the harsh landscape of Ascalon. I felt a general sense of stability by the time I casually tossed a lich into a volcano. His friggin’ imps were more of a problem than he was.
Vertical Progression is not inherently bad, although it certainly can go that way (WoW). Vertical Progression is GOOD when it gives you a sense of progression, and I really do think that’s the key word there. It allows a developer to make a player focus on a piece of content and get used to how it works, then it can make that content more complex and force the player to learn things again. So long as the player is actively engaged and getting better at playing your game, I think vertical progression is doing its’ job.
When vertical progression is just about getting an arbitrarily more powerful piece of armor so that you can go face the exact same level of difficulty it’s not really progression anymore. It’s just rehashing old crap and putting a shinier coat of paint on it.
So in conclusion; GW1 really wasn’t that great. Also it’s bonus missions are horrible.
