Guild Wars 2

1. Crude comparisons are useless.
Comparing certain skills across classes is a useless endeavor. Comparing thief’s Channeled Vigor to say, ranger’s Troll’s Urgent will get you nowhere when you try to claim one of the two are overpowered. The skill itself matters very little to the question of its balance in the game. What matters is the synergy, that’s why all the buffs to ele, for example, are useless. They do not deal with synergy, just with numbers at face value. Signet of Air’s buff was good, and the skill now is amazing, yet you see actually 0 people using it in ranked because it does not play into the meta. It offers no counterplay to the current meta’s speed. This could also be said about your proposed buffs. Buffing thief’s s/d (for example) will be useless because s/d was good in a slow meta, where it fits. This meta would chew up and spit out any and every s/d thief that comes near it. Before stating your proposed game changing buffs, analyze the meta and where all classes fit to see if your changes would actually impact the game in a positive way.
2. Don’t let your emotions guide you.
Usually when someone gets stomped by a very strong build or skill, they jump right onto the forums and complain about how powerful the build or skill is. Don’t be that guy. That guy will say something insane like, “Moa 2 stronk, pls delet” and expect to be respected by any of the player base, let alone be taken seriously by the game developers. This game is very intricate in its design. In fact, it’s the most intricate game I’ve ever played in my entire life, and this may hold true for the next decade. To cloud your critical thinking faculties and to take effort away from your logical thinking ability is a 1 way ticket to be laughed off of the forums.
3. Treat the devs like human beings.
Do not lower yourself to the rank of a sycophant just to get the attention and consideration of devs, and most definitely do not call each and every dev a moron because they do not think the way you do. The job of a dev for this game is incredibly hard. It’s the type of job where a few buffs to a class could change the entire meta. Where multiple buffs to a class could do nothing at all, and maintaining the role of each trait and skill for the sake of not warping the goal entirely. You’ll have to buff, but not too much. You’ll have to nerf, but not too much. And they’ve been doing this job for a while, whether it be a good job or not. Do not assume that you are better than they are because you can theory craft an amazing build. We all can. Maybe the build isn’t healthy for the meta.
4. Be open to criticism.
I’m not saying that you must pretend to be happy that someone said that you are a brain dead novice who can’t stay on a node long enough to get out of bronze. I’m saying that if someone has a genuine argument against your propositions, read them, consider them, and decide if they are valid or not. Do not simply assume you are right and near omniscient enough to deduce the health of your balance suggestions. If you think Warrior is broken OP, read peoples’ reasons as to why they disagree. Do not expect that the first person to read your post will be a dev, and do not think that a dev will read it at all. These are the forums. The main consumers of the conversations here are other players. See their point of view.
5. Do not expect change.
This last point ties in with all the previously mentioned points. Do not think that you will bring on a game changing nerf or buff to something that will end up making you happy (or ultimately not). This website is mainly for discussion, theory crafting, helping people, and most importantly, collaboration between players. Once you have rid your mind that the devs will come to a consensus and follow everything you proposed, you will end up making more logical threads that could actually influence change.
(by the way, I know that I’ve broken basically all these rules before, no need to mention that)

Logic and thoughtfulness OP, plz nerf

But where is the fun in gaining internet sympathy from other irrational players?

On #3 Developers

Here’s my beef with developer interaction: there’s barely any! We can’ get basic class design philosophy answered. It’s one thing to have a goal and do poorly, but we don’t even know what the goal is!

The biggest unanswered question surrounds elite specs. When elite specs were first revealed, ANet said they were side-grades and not intended to be more powerful than a core spec. It’s now over a year since HoT launched and elite specs are still blatantly more powerful than core. But ANet has yet to come out and say, “It’s still the intent that core and elite are equal; we goofed” or, “We changed our minds; elite specs are stronger than core.”

A few paragraphs every few months saying what they thing is too strong or too weak and in what areas would be sufficient.
