This post is made entirely with the assumption that healing, on the scale that druid provides, will be vital to clearing raids. If your issue with this post is because of your concerns with the dps meta, healing being useless, etc., please voice your opinion elsewhere.
I must make some speculation on the power of druid healing because we do not have skill coefficients. However, after seeing the numbers in the stream with no healing power, it’s hard to argue they will not be competing for strongest healer in the game.
The Elite Specs:
Currently we have two largely healing elite specializations. The first being druid, the second being tempest (with a staff). The main issue: druid only needs one trait line to be an effective healer, while tempest needs three (water, arcane, tempest). This allows druids to run dps traits (marks, skirm) in addition to getting amazing healing options (with quick draw you can keep the flower wall up half the time, or chain two back to back!). Tempest you must run a very strict template (powerful aura, evasive arcana, elemental bastion) and skills (all the aura shouts) to attain the healing prowess of druid’s staff, celestial form, and glyphs.
While tempest might be able to outcompete druid healing depending on celestial form’s cd and shroud buildup, tempest will lose massively when it comes to supplementing damage. (you can run spotter, frost spirit, AND outgoing damage glyph as a druid, c’mon now!)
The Core Specs:
Ventari is meant to heal, and roy recently posted on rev forums that ventari has “sustained” healing while druid was “burst healing.” You can get some pretty high numbers on the delayed tablet heal especially with the insane amount of outgoing healing rev can build up so I won’t speculate much on ventari healing until this weekend. As with druid, this one traitline provides formidable healing. However, due to rev’s profession mechanic, I doubt ventari will be anything more than a supplemental healer.
Guardian. The spiritual successor to monk. (1) The aegis application on guardian is being buffed (shield 4), and pure of heart is an extremely unique and clutch way to play healer (dare I say protter?). Too bad it has pitiful base healing and coefficient. Communal defenses will probably see play in raids because it has no target limit. I really want aegis guard healing to be wanted in raids, and hopefully we can see some buffs to pure of heart and aegis duration OR cd on communal defenses for HoT pve. Guardian has amazing heals per second, but is missing any good way to burst heal. (2) You need to spec into valor (communal), honor (EVERY gm trait is good), and virtues to get a good amount of heals per sec. This spreads your traits thin and avoids any dps lines, like tempest.
I am largely unfamiliar with engie healing. They have some really awesome healing traits, and I’m fairly certain we will see a medkit buff soon. It looks like inventions with alchemy can provide some good healing, but will lack ranged burst healing (water blasts are great but limiting position-wise).
Mesmer mantras are cool but I think chronomancer will have enough on its plate keeping alacrity, quickness, and other fun party support up without the need to supplement healing.
tl;dr
Druid and Tempest provide excellent healing options that will see use in raids. Some healers (guardian, tempest) require too many traitline investments compared to other healers (druid, ventari), therefore reducing their effectiveness at other jobs. Please consider these ideas and builds in the upcoming beta so that we can have a discussion on the future of viable healers in GW2. I want to see more than ele and druid in the healer role for raids.
Who would you like to see as a viable healer in raids, and should you need to invest in multiple traitlines to provide viable healing?
Ps – we need some stat spreads with ferocity and healing power for healer deeps. And yes I’m salty about tempest.
