Elementalist vs. Mesmer
Elementalist – Jack of all Trades and honestly good in everything. Great aoe, self and team support, can be tanky but not all at once. Mesmer was nerfed too much, higher survivability than elementalist, cause monsters tend to focus on clones and phantasms and after recent patches they are nearly immortal but for sure worse damage output.
Ele has much better personal dps, while mesmer has much better group support, at least from a pve raiding perspective. As a result ele is replaceable by the other classes that do damage at or above its level, however having multiple eles is not bad for the group as long as all the necessary support is covered. Mesmer on the other hand is irreplaceable for a group and the most valuable class for increasing group dps. However once you have one to cover the alacrity/quickness, it generally doesn’t help much to add more.
