Guild Wars 2

The first and most obvious problem with this suggestion are simple mechanics. These are powerful traits, with a wider AoE the cost vs result scale would be tipped. My goal is to find a medium in which build choices open up without making certain team compositions overpowered.
For scale comparison:
Standard symbols are a radius of 180

PvE
No problems foreseen.
PvP
Mesmer – Giving mantras too much of a boost, in cahoots with a bunker guard, would be ridiculous. With 450 range, its close enough for a player to leap to the mesmer to apply pressure, while the mesmer has to multitask between active defense, positioning, and burst damage.
Elementalist – Buffs the supportive side of ele in a rarely used trait tree.
Necromancer – Buffs trait trees which are pretty much useless on a master trait level.
WvW
Mesmer – Buffs an entirely different role to the mesmer. 450 range isnt quite enough to be safe from all of the aoe, forcing the mesmer to choose between survivability and damage. Giving mantras shout radius would be too much.
Elementalist – Gives d/d eles more utility, as well as staff eles team support for their backline comrades.
Necromancer – Again, buffs two trees which are very lackluster. Death Shiver could be pretty strong in an organized group setting if 2-3 necros worked together, but cleansed easily because of the time it would take to achieve high vulnerability stacks.

A big concern in WvW for these proposed changes would be the huge buff to group stability. I think the sacrifices in terms of trait/gear setup and team composition would balance out. The new mesmer in terms of group stability and condition cleanse would be pretty similar to a guardian, except for the fact that a guardian is still a lot more tanky with shelter and renewed focus, plus his shout radius is bigger than the mantras.

In the end, theyre ideas that might be beneficial and might not be. What ya think?
