Elementalists are extremely strong for PvE and Dungeons. In Open World play we tend to use a Staff mainly in fire attunement or a Fresh Air D/D build.
In dungeons we ckittene the staff for high individual DPS which is particularly effective against trash mobs. The more popular options tends to be S/F or S/D with Lightning Hammer conjure as our main DPS weapon. This build allows us to stack a lot of Might for the party which will increase everybody’s DPS rather than just your own, we can also provide perma-fury which is an additional 20% critical chance for everybody.
Ele’s excel in everything really, we’re wanted in Dungeons, World Bosses, WvW, even PvP sometimes x)
However don’t get rid of your mesmer too quickly. They can be extremely strong if played right and some of the best players in my Guild main a mesmer and are a huge help to other members because of their portal abilities. They’re also wanted in WvW for their Time Warp ability and again, portals are always helpful. They’re also annoying as heck to play against in PvP so I don’t really see a downside to them.
In fact I’ve been thinking about making my own Mesmer lately, they seem to have better survivability than Ele’s do and I’m the kind of person who normally gets past difficult parts before others so I think portal would be great for that.
, ele have many viable build for Pve, d/f, s/d and staff but the most usefull things is the FGS
