EDIT: Please note that this post was written before Global Agenda 1.3 was released. This was before solo PvE was possible. The open world did not exist when this post was written. Please keep that in mind. (In other words, this post may be irrelevant.)
In Global Agenda, Medic is the only class that can be a dedicated healer. Robotics can plant medicrates that heal nearby allies for a fixed amount every second or two, and they can buff allies’ damage through planting sensors or defense through planting forcefields between allies and enemies. Medics can buff as well as robotics, if not better, and they can heal other characters anywhere on the map.
Every class in Global Agenda has three talent trees. All classes have a “balance” tree that provides general improvements like a bigger power pool, faster power recharge, and extra defense. The other two trees are specific to each class. The medic has a healing tree and a poison tree.
The poison tree is a design failure for three reasons.
Reason #1: Poison Medics throw off Team Balance
In Global Agenda, you always play with a team. You play 4-man instances if you’re doing PvE, and 10v10 matches if you’re doing PvP or AvA (Agency vs. Agency; conquest).
Global Agenda balances teams based on class composition. Each team will have roughly the same number of medics (there may be one more on either team). If each team has three medics, but one side has two poison medics and one healer while the other has three healers, you’ll notice that, if skill is even between the teams, the team with the healers will always win.
Keeping allies alive in Global Agenda is paramount—an ally waiting 10 seconds to respawn and running back to the fight location is not helping his team for as much as thirty seconds per death. Perhaps the medic-spec imbalance would not be an issue if poison spec medics could do significant damage, but poison medics are easily foiled because they are reliant on poisons and debuffs that any heal-specced medic can dispell with the press of a button once per minute.
Poison medics act to spoil team balance. Especially when all PvP is through pick-up groups (you can only have a 4-man group when queuing for PvP, but teamsize is 10), a DPS medic takes away a surprising amount of utility from his team because others cannot adjust to fill the roles needed—only medics can fill the role of dedicated healer.
Reason #2: Poison Medics are Redundant
Other classes have DoTs. Other classes are better at doing damage. Why let a support class spec so that it can do comparable damage to classes that are meant to do damage primarily? Other classes do what poison medics do—everything except healing on demand.
EDIT: And other classes can use off-hands and certain weapons that do the same kinds of debuffs that poisons allow. If anything, the Recon class should use poisons. Otherwise, giving medics the ability to counter medics is poor design, considering other classes can just shoot the medic who is healing and kill it before moving on to the teammate he was earlier healing.
Reason #3: There is No Soloing
Why do you need a DPS tree in the medic class if there is no reason the medic should be using it? Damage trees became popular among support and healing classes in other MMOs because healers needed some way to solo so they would be casual-friendly—but you never solo in Global Agenda!
The Third Tree Should be “Buffs”
HiRez should remove the poison tree and replace it with a buff-centered tree that gives bonuses to different buffs’ durations and magnitudes. A buff-centric medic supports other characters and will be able to heal effectively at any time.
I’m not against medics having a few offensive off-hands—but allowing the medic to essentially substitute his or her entire healing capacity in favor of dealing damage has too many downsides and almost no upside.
[EDIT: I'm arguing that medics shouldn't be encouraged to DPS through dedicating an entire tree to it. I am NOT saying that medics should be unable to defend themselves. Medics should be able to do reasonable damage to foes, but they should not be encouraged to eschew the point of their existence, healing, in order to do a little more damage.]
