I would like to discuss more about boons. Most GW2 players have some knowledge about. We at Guild Wars 2 Stratics want to delve a little deeper into the topic. From the Guild Wars 2 Wiki Now as a player you would want to have boons on you. There are 7 boons total. Like the above exampe in the wiki quote. If you had 2 players casting the regeneration boom it does not stack or double the regeneration, it just adds time to the spell. So if mutiple players are casting the same boon in any profession, they are not wastiing their time since it adds to the duration of the spell on others. All boons just stack on top of the other boon. Now the 7 boons are (from gw2 wiki) Now the Aegis is only exclusive to guardians as pictured above. Each boon can be triggered by spells of a particular profession. Let me use another example from the guild wars 2 wiki. I chose the Protection Boon. Skills that grant protection By profession Guardian "Hold the Line" "Retreat" Martyr Protector's Strike Shield of Judgment Signet of Judgment (passive effect) Symbol of Protection Engineer Elixir B (randomly among other boons) Elixir H (randomly among other boons) Throw Elixir H (tool belt skill, randomly among other boons) Elementalist Glyph of Elemental Harmony (while attuned to earth) Ring of Earth Signet of Earth (passive effect) Now the above is just a few listed over all on what you can do with that boon. So a player choices wont go to waste and may extend gameplay in a huge battle since boons will stack but only for duration. With different professions using different boons and only able to stack that effects duration only makes the boon system pretty balanced. Boons can be removed so even with stacking them does not protect the player from these 2 spells Corrupt Boon Feast of Corruption So in PvP and PvE the boon system will play a huge part of the new system.
