Re: Ability discussion: stations, beams, and hose.
In GW, I mostly used the default heal station. The armored one got buffed in GW2 as it wasn't as good, but I recall people parsing it out and it's still not as good but at least it's closer in effectiveness. The cheetah station is somewhat amusing to hear as it heals. When I see that station more than the other 2 as a plant, I go after it heavily as it's both very powerful and easy to take out.
Once GW2 came around, I've swapped almost fully to the heal beam, but I do still the stations on occasion, especially when soloing as a scientist on the flag of power for quests and I have no one to use the beam on. The flag is also about the only time I use my bling armored station!
My main issue with BfN's hose is that one of the reasons I play GW and GW2 over other multiplayer shooters, even TF2, is that healing characters tend to have to choose between healing or attacking and yet the GW games let us do both so we feel less restricted, and the hose goes right back to forcing you to choose and focus on one or the other, especially if your heal thingy is down. As someone who doesn't go for the assault scientist, I really prefer the GW/GW2 model where I can focus on healing while simultaneously being able to defend myself.
