As far as combat, it’s quite different from WoW. Don’t think of it as a tab target game, think of it as an action combat game. You should actively be dodging, blocking, using various forms of CC (blinds, stuns, slows, etc.). You should be using both weapon sets in combat as well as your 5 extra healing/utility/elite slots. You don’t have 5 skills in combat, you have 15. As far as CDs, it’s expected that the longer CD skills will be used with thought, not spammed every CD, and mixed in with the fact that you have a second weapon set to switch to, combat in this game is very fluid and fast paced. Some have even called it too chaotic and wish they could go back to the simpler WoW style combat. Although most CDs in this game are not that long – most weapon skills are between 10-25 seconds (unless you play Elementalist but they have long CD’s to make up for the fact that they have twice as many weapon skills as everyone else).
Dungeons in Story Mode are not hard. They’re fun and meant as an introduction to the dungeon as well as an opportunity to play through the main story. The harder dungeons that everyone talks about are “explorable” mode. Each dungeon has an Explorable mode in which you can take one of several different paths. These are GW2’s answer to hardcore PvEers who in other games would have done Hardmode dungeons or raids. They require the same type of skillset and teamwork and are supposed to be endgame content, except you can do most of them pre-80 (the first one is actually only level 35).
Oh I forgot your point about ranged classes. For starters, every profession (not class in this game) has a variety of weapon sets. No profession is ranged or melee, everyone has options to do both. Also, every class has a multitude of Cc abilities like stuns, blinds, slows. Some also have stealth. Some have knockdowns/knockbacks. Some have protective shields, some have skills that reflect or simply protect you from projectiles. Some classes have various types of “pets”. So there are a variety of ways for a person using a ranged weapon to kill stuff regardless of the type of enemy you face and if you prefer melee, you can do that instead and only save your ranged set for certain circumstances.
This are some very interesting thoughts and ideas which i admittedly did not have.
For one, i do know the idea of swapping weapons for another set of skills so you have more skills to use while waiting for other CDs. But at least for me, i like to stick to the weapon i like, then again that’s my own personal preference which i think i should change so good point.
Regarding dungeons, well in that case i guess i can try out story mode at least.
But with regards to ranged, i don’t really agree. Yes they have the option to stay at ranged or melee. But i feel like they ’re kittening their own survivability at melee. At least in pve. But then again i might be wrong so any ranged experts can give their opinion on this?
