Bleeding, in many respects, is the bread and butter of Condition based builds. As it stacks in intensity this means you can apply multiple Bleeds, with each Bleed dealing a certain amount of damage.
For example, if an Engineers Explosive Shot causes Bleeding for 4 seconds and each second of Bleed causes 100 damage, you would deal 400 damage for the duration. If you fired twice in succession, there would be two stacks of Bleeding active, with each stack dealing damage per second, causing a total of 800 damage over 4 seconds.
In Condition based builds, it is paramount to achieve a large number of stacks in order to deal damage as quickly as possible. It isn’t uncommon to see stacks of Bleeding in excess of 10+ stacks, but the total cap on a single target is 25.Almost all professions, in some form, have access to Blind. Some professions have a considerable amount of skills that cause Blind and effective use of it can be the difference between life and death. As the above suggests, when you Blind someone their next attack against you or an ally will miss. Skills that cause Blind tend to have long cool-downs due to their potency but can be vital in mitigating damage.For example, as an Elementalist if you see a Warrior about to aim Kill Shot, which has a clearly defined animation (the Warrior gets down on one knee) casting Blinding Flash will cause him to miss and likely prevent a huge amount of yours or your allies health disappearing.
Burning as a single Condition (versus 1 stack of Bleeding) offers the highest damage out of all Conditions (although 25 stacks of Bleeding would surpass anything) and is reflected in the fact you cannot stack multiple Burnings. If you apply Burning twice, you will prolong its duration only. In many respects, this causes several problems for professions and players that choose to use Condition builds, as there is inevitably a skill overlap that causes an individual’s skill/skills to become redundant. Effective skill rotation to keep Burning active on your foe is the best method to buy guild wars 2 gold and I would recommend that during fights, you open with any skills that Burn so that the damage to them quickly stacks up and over the course of the fight, will allow you to use any Burning skills again.
